Durastop upgrade

[DougD]

OK, since I'm the one that brought this particular possibility to light

I'll be trying it, on the fronts only for now, within the next week.  My 103K brakes are finally starting to get noisy and are looking a wee bit thin.

Front rotors are a touch over $100 each, slotted & drilled.  The matching ceramic pads are about $50 for the set.

Rear rotors is where it gets ugly.  325mm ones are around $130, the 330mm (likely what I have) are almost $170! each.

Pads are around $60 for the rear.

All totaled, this upgrade would run around 650 for the 330mm, 570 for the 325.  If these work as good as the ones I put on the Impala SS do, this will be one of the best bang for the buck upgrades, AND keeping it all GM.  Pads also carry a lifetime warranty, and I've used that on the Impala ones once (not for being worn out in total, just had a bad hose that was dragging a caliper and really wore out a side).

I'm not sure if the rotors carry a similar warranty, will find that out when mine arrive.

Details and pictures will accompany this when it happens.

Get to work lazy!

[WILDFIRE]

good find, can't wait to hear the results

[DougD]

Can't "get to work" until goodies arrive.

[Web]

Will these type of parts fit a cladded 03- Z71? I will need brakes soon an would like an upgrade also...

Brakes aren't different between WBH and cladded, so yes.

[DougD]

Brakes have arrived, will be picked up today.  Pics to follow once they are in my hands.

done yet???                 

[CodeBlueEMT]

 We've been waiting patiently ( 103K miles ) for you to try out this upgrade. Looking forward to your review.

This may be tomorrow's project.  Son is out of school, so I'm somewhat trapped at home entertaining him

Seems like a great time to rip in to the truck.

[DougD]

 Shayne

Me too.

If I get half the benefit of having put these on the Impala, this is a no-brainer.  PRobably cheaper than regular replacements, too.

Of course I still need to do rears.

[DougD]

And here we have the rotors

[DougD]

And the pad kit, complete with hardware and a tiny packet of silicone lube.

[DougD]

Tomorrow we shall have the install pics and completed results.

[DougD]

Should also point out that I'll likely die from this upgrade, as the rotors are made in China.  The pads are from the good old U.S. of A.  Handling the rotors, however, will likely kill me from an overdose of lead paint or something.

Only if you eat the paint chips!

Looking forward to the pics and write up..don't disappoint

[ygmn]

Did you get new calipers or stock?

Before doing this please go test..

fill up truck..

find big place...

Get up to 60mph..
and slow to stop...

measure distance..

repeat few times to get good average..

then change out parts and repeat test..,

real world numbers.. or
do I need to call mythbusters to do this?

Call someone else.

I use a butt-o-meter for this kind of testing.

No new calipers, no need for them.

[jimbo53188]

gotta love the delco stuff ,lifetime warranty on the pads & 12 months on the rotors.(nobody else will warranty drilled rotors for 12 mo. )

 Maybe you'll get the GHB flavored rotors instead of the lead paint.

[DougD]

Ooooh!

I'm gonna go outside and lick them right now!  If I'm lucky, they also have toad juice on them.

[jimbo53188]

how bout cop brakes part # fronts 2 or 4wd ATD785P, rears 2wd only ATD974AP.
apparently the police don't use 4wd tahoes.

[DougD]

That's a ceramic pad.

Mine are ceramics.

[avdavidw]

Ooooh!

No matter how tasty they look, do not lick the rotors!

[jimbo53188]

it's a very special compound for no fade high speed performance,perfect for towing 

[DougD]

[DougD]

Headed to the garage NOW

[Web]

well... it's been 5 minutes... you done yet?                                     

[FlaBouy]

Will there be pictures involved.....    without the fence, of course... 

[DougD]

The butt-ometer states that there's a 40-50% improvement over where the truck was before the upgrade.  That would figure to be perhaps a 20-30% gain over OEM new brakes, in my opinion.

Matched with a set of rears (yes, I think I'll bite the bullet and order a set in a week or two), should be quite a notable improvement overall.

Pics and docs to follow.

[DougD]

We start with a picture of the stock setup.  Second image is the caliper mounting bolts, once removed.  Requires a T55 socket.

[DougD]

We follow this with the retaining bolts for the mounting bracket.  This bracket holds the caliper in place, and mounts the pads on sliders.  This bracket also keeps the rotor from coming off.  The second picture is a shot of the bracket, once removed.

A tip for removal of this bracket - turn the wheel to the opposite direction of the side you're working on.  This brings the rear of the brake assembly to you and makes it more accessible for this part.

I used an impact wrench as they were pretty darned tight.

The somewhat shiny pieces on the bracket are the sliders.  These are replaced.

[DougD]

Once the bracket is removed, the rotor comes straight off.  Do note that there may be retaining clips from assembly on one or two lugs.  I cut these off and discard them.

Second image is the caliper.  I was able to gently position it on the lower a-frame to support it without damaging the hose.

[DougD]

Now we have the new rotor, mounted.  Second image is the bracket with the new sliders.  These are to be lubed, in the Durastop kit there is a lube packet for this.

[DougD]

Important to note - there is a specific right and left rotor, not interchangeable.

Now we have the pads mounted in the bracket.  In my case, the OEM had two warning tabs on the outer pad.  The Durastops also did.  One on the inboard pad.

Next image is the caliper and bracket remounted.  Note that there are collapsible boots on the caliper retaining bolts - ensure these are not bunched up or torn.

[DougD]

And finally, a straight on shot of the completed install.

Note that all photos were taken by my 9 year old son while I worked

[GreatWhite496]

In that case I don't know who did a better job...him or you...looks great

[CodeBlueEMT]

 Doug, did you order these from a local dealer or use a source from the site?

 BTW, nice job by your son on the install pics and your unbiased review with the  ever so proven butt-o-meter. 

 Shayne

[Web]

Looks good.....  pretty quick too....You made it look easy.... hope it is...

[Loggie]

very cool but I have to ask, no paint while you had them off

[WILDFIRE]

nice write up, glad to hear of the improvement 

[jimbo53188]

have you had a chance to run at freeway speeds yet? iv'e read that drilled rotors hum at freeway speed.

[DougD]

My local dealer.  I'm trying to get them on board as a partner.

[DougD]

Well, having the right tools is always a help.  Having done countless brake jobs also helps

[DougD]

have you had a chance to run at freeway speeds yet? iv'e read that drilled rotors hum at freeway speed.

Just came back from a trip to Tampa.

Have also had slotted & drilled Durastops on my Impala for 4-5 years now.  Wherever that rumor comes from, I've not experienced it at all.

[DougD]

Paint what?

It's filthy thanks to the road construction I endure daily.  It's also an everyday & work truck.  No need to make it purdy.

[ygmn]

he takes better pics then you.... should have used him on the water pump write up..

PS.. are you doing the rear too?

I see no pictures.... curious as to park brake setup...

[ygmn]

PS where is the jack stand?

all I see is a jack...

tssskkk tssskkk bad shop habits...

[DougD]

Stands are a bit further back under the chassis, just not visible in the pics.  I >NEVER< work without stands.

[DougD]

Water pump was fine as a writeup

Rears will need to be done.  Stupid rear rotors are more $, especially the 330mm.  The 325mm aren't that bad.  $40 difference per rotor.

[Web]

One more dumb question from me....

Are 2 wheel drive brakes and 4 wheel drive the same? In other words are these available for 4 wheel drive?

[DougD]

Honestly I didn't look, but I believe there is no difference.

www.acdelco.com and run through the catalog.

[Mr_Scary]

I'm with Loggie, where's the paint on the calipers

Looks like a great job!  Be calm when you first drive them.

The right tools is always a must, especially the T-55!

Nice job and thanx for the pics.

Mr. Scary

[jimbo53188]

Just came back from a trip to Tampa.

Have also had slotted & drilled Durastops on my Impala for 4-5 years now.  Wherever that rumor comes from, I've not experienced it at all.

thanks for the great write-up,i ordered pads today but am still on the fence with the rotors, i have to admit the LOOK is excellent and you can't beat the 12 mo. warranty on the rotors.

[DougD]

Honestly, if you're wanting them just for the look, it'd be a waste of money unless you have different wheels.  They don't show through well.

Also, since you have a 2500, if memory serves you can only get Durastop slotted & drilled fronts.  You'd have to run through the catalog as well, to be 100% sure.

[DougD]

OK - the rears have arrived and are installed.  45 minutes for this set as I couldn't use air tools due to the arrangement of bolts

We start with an image of the parts - first a rotor, then the pad kit.

[DougD]

Moving on, we have the stock arrangement and a closeup of the unusual caliper pin arrangement.

[DougD]

The tools needed to remove the caliper bolts - 14mm socket on the bolt, 19mm wrench on the clip-like head.  Second picture shows what's left after removing the caliper.

[DougD]

Next up - the bolts that hold the pad and caliper bracket in place (pads are easily removed prior to removing these bolts).  Note that these are 18mm, which is a slightly uncommon size for the average toolbox.  They are also very tight due to factory threadlocker.  On the fronts I was able to use the trusty impact wrench on these corresponding bolts.  Here, it was breaker bar and brute force.  Bracket removed from truck in second image.

[DougD]

Bracket with new slides installed, then (if even visible in shrunken picture), the sliders with the lube applied.

[DougD]

After pulling off the rotor, this is what the fortunate folks and those living in a gentler climate will see, nice clean, fresh, unrusted and unsiezed e-brake components and solid backing plates.

[DougD]

New rotor installed, new pads in bracket

[DougD]

Finished product.

One note - when reassembling, I suggest pulling the caliper pin from the boot and applying fresh grease.

[DougD]

45-50mph panic stops - not a single bit of fade, and not a single bit of anti-lock engagement.

Stands the truck on its nose.

Total investment - around $600 and 1.25 hours.

[Intimidatoruag]

great write up ... looks like on the your one front shock it is leaking and needs to be replaced ....

[DougD]

great write up ... looks like on the your one front shock it is leaking and needs to be replaced ....

That had to be from some of the road construction, the shock isn't leaking.  I couldn't really ID where it all came from, there was some splatter under that whole area.

[ygmn]

Thanks...

I take it you did not replace park brake shoes or parts?

[DougD]

Thanks...

I take it you did not replace park brake shoes or parts?

No earthly reason, didn't you look at the pics?

[ygmn]

I was interested in one of the bottom spanner doohickey thingy that spreads shoes..

as my 2002 might have the issue of not working properly...
(never know as never used)

[DougD]

Mine are never used either.   However, all hardware looked good.

[GreatWhite496]

Doug..nice write up..this is something I am planning on for next year.

[jimbo53188]

excellent write up errr.. tutorial , i was gonna post my install when my stuff arrives but you did such an excellent job !!!! just two more lugs anyway!

Give me the good info jimbo since I am 2500, too

[jimbo53188]

will certainly do so..  jim

[jimbo53188]

well my brake parts are here,i work for a auto parts distributor so i ordered directly from raybestos, went with advance technology performance rotors and pads. install will be shortly, have to work around mother nature, UPDATE: one of the raybestos rotors i received was boxed wrong so i obtained a durastop replacement,notice the similarites.the durastop brake parts are made by raybestos. only reason i point it out is the durastop rotors are $129.79 and the raybestos are $106.79 @ www.rockauto.com

[jimbo53188]

brake pad info.....Application Specific Shims for Lowest noise and Longest life
Quiet Coated Hardware for Maximum Noise Suppression
Advanced Formulations to deliver increased stopping Power
Electronic Wear Sensors Where Applicable
Vehicle Specific Slots, Chamfers Ensure Quiet Operation
PS. we've sold these to the county garage for use on squad cars and they routinely see 1200 degree's and still no fade!!

[MS03 2500]

Jimbo can you post the Part numbers for the rotors

[Big L]

Great write up Doug and tell your son he has a future in photography if he wants.

[jimbo53188]

Jimbo can you post the Part numbers for the rotors

ST56828R , ST56828L , ST56829R , ST56829L, front pads are ATD784C , rears ATD785C. fyi the pads used on the rear of the 2500 are the same as fronts on a 1500.

Thanks sir

fyi the pads used on the rear of the 2500 are the same as fronts on a 1500. You are kidding

[ygmn]

.... leave it to GM to spare no expense designing a part

UTILIZE is better term...

allows for lower costs due to larger qtys.

[jimbo53188]

fronts are in!!!!!!!!!! i'll post pics of the finished install since doug covered it pretty well, apparently south of the border they use loctite in generous quantities,you'll need an impact and/or BIG breaker bar to over come the resistance,otherwise it's pretty straight forward.the results are well worth it: light pedal pressure and no fade at all, can't wait to start towing season!!     rears next...

[jimbo53188]

here's the sequel.....the results are excellent.. best mod so far... 

[MS03 2500]

Looking good Jimbo, let us know how it stops now.

[jimbo53188]

Looking good Jimbo, let us know how it stops now.

i won't be towing til' the spring BUT' the av' shoulda come from GM this way. stops are short and pedal pressure is light, like doug said "it puts it on it's nose"

[MS03 2500]

I scheduled for brakes shortly (well about 2 months ago) think I go with this.   

[DougD]

Like I said, I've been hooked on them since I put them on the Impala.  That's honestly at least 7-8 years now.  I will drop these on any GM vehicle I have as soon as I eat through the original set.

[jimbo53188]

just thought i'd add this...we recieved about 7 inches of the white stuff in the last 24,and the end of my street is a downhill slope, in the last 2 yrs. when braking on the slope there's a dip that causes one wheel to momentarily loose traction and subsequently the ABS kicks in with it's familiar growl!!! but alas no more!!! my wife and i drove around shopping , putting on 200 mi. and not once did i need ABS.could be the brakes now function as a balanced entity, none pulling any harder than the rest  . iv'e always thought the oem brakes a little lacluster in ability.when towing i always put more power to the trailer brakes than probably needed just to compensate. out of all the mods,this ranks #1. a special thanks to doug for bringing this to light!! i thought the performance rotors were a "race car" gimmick and not beneficial to the street,  THANK DOUGD!!!!!!!!!!!!!!! bring on the towing season!!!!!!!!!

[Dune]

I'll have to check out this mod. I've been needing brakes now for some time.

[MS03 2500]

Not bad pricing either I priced it at RockAuto.com with parking brakes and hardware it was 701.00 with shippping , but my neighbor works at Auto supply place so going to see what he can get for.

[AvalancheZ66]

lol totally     but never the less, cool stuff

You wanna do it, I can get it ordered for you here and you can even come here for install.

Granted, I don't have the snow to use as a test for ABS   but I have YET to be able to kick the ABS in.

I too thought that slotted rotors were more appeance than function in a simple street vehicle, until I put these on the Impala.

Quite simply, any GM vehicle I own that has these available WILL have them as soon as the brakes need replacement OR as soon as I can convince my wife we need them

[jimbo53188]

i agree they'll go on every vehicle i own that need brakes.the fact that raybestos makes the parts means they're available for lots of non GM vehicles.

[erickpl]

This is great information.

I'm coming from an Audi and a BMW car, so my wife and I are not too thrilled with our Avy's brakes.

Can you post the P/N's for the front and rear rotors, as well as which brand you used?  I've seen the Durastop ones and the Raybestos ones.  If I call an autoshop and ask for slotted/drilled rotors for my Avalanche, will I get either the Raybestos ones?  When modding my other cars, I've been told "that's not available for your vehicle" and it pisses me off.

So to keep the guys behind the counter unconfused, if I had the P/N's I needed for a 2005 Z71 Avy for all four corners and the pads for each that'd be great.

[dakota745]

Hey doug,I am sorry I tried emailing you,for some reason it shows error:( I want to order this stuff today,Did you get the stock rotor size?and what pads should I get?anything else I should know when ordering this stuff?thank you:)

[jimbo53188]

I tried that.  It only gave me Guardian parts.  Is there something in particular I need to look under besides 2005 Chevrolet Avalanche?

just looked and all the part #'s show up for me  ST56825L , ST56825R are the fronts, ST580165L , ST580165R are the rears.pads for the front are ATD785C , rears are ATD834C.

[erickpl]

Thanks for that. I had been using the Avy as the vehicle of choice and I guess that is why I got limited results.  I did some searching on Raybestos site and found all the P/N's for the front that you did, but had a harder time with the rear.

Again, thank you for the information!!!!!

[jimbo53188]

you're welcome !

[DougD]

I haven't had a chance to study the Z71 rear options, do they have the two different sizes?

[erickpl]

Honestly I'm not sure either.  I have those parts that jimbo provided, but I'm not at the point where I'll be doing this upgrade.  I'll research it in much more detail to find out exactly what I need before I do it.  When I get the information, I'll post what I find.

[jimbo53188]

02-04 have two sizes available, 05 is only lists one.

The 325/330 nightmare

[jimbo53188]

The 325/330 nightmare

different part # in 05', gm could'nt even use one of the previous rotors listed,had to come up with a new one ! checked delco's website,same thing 

[johnt]

Can someone comment on the 325/330 nightmare? I remember going through this when I replaced my rear rotors the first time.  The rotors I had to go with appeared thicker (wider vent), but I don't remember if they were 325 or 330.  Is there a rhyme or reason to this, based on VIN?

I'd like to do this upgrade since it's time for new brakes, and would obviously like to get the right rotors the first time.  :D

BTW, this is a great site.  I've been lurking for about a week and picked up a bunch of tips on things that were bugging me about the AV.

John

[DougD]

Many believe, myself included, that Z66/Z71 gives you the bigger rotors.

Honestly, the best solution I know of is a visit to a dealer with your VIN to be sure, OR removing a rear rotor and measuring it.  Thickness and diameter are different - not just the diameter.

[SoberBiker]

I have been trying to make heads or tails out of the info in this thread for about 4 days and when I go to the sites listed I can't find the exact numbers given.

I have a '03 Z71 (4 wheel drive) w/17" wheels and I am wanting to upgrade to the slotted and drilled rotors (Frnt & RR) w/ceramic pads.

Could any of you give me the part numbers needed to order the set-ups for this application?

If you would email me at jcw1950@yahoo.com it would be greatly appreciated.

Sober, I too have an '03 Z71 (1500, right?).  Going by the pictures on the rockauto site, it looks like my truck gets the 330x96 rotors.  Your's probably will as well, though you may want to double check.  Now if you want to trust a newbie, I've just gone through the rockauto and acdelco sites and here's what I've come up with:

Raybestos parts:
ATD785C for front pads
ATD834C for rear pads
781PG for the parking brake shoe
ST56825L & R for the front rotors
ST56919L & R for the rear rotors

AC Delco parts:
17D785CH for front pads
17D834CH for rear pads
17781B for the parking brake shoe
18A1256 & 18A1257 for the front rotors (L&R)
18A1646 & 18A1647 for the rear rotors (L&R)

HTH,
John

[SoberBiker]

Thanks John

I'm glad I asked cause that is completely different than what I came up with. I'll check your numbers and see if I can get them to come up. 

BTW...what sites were you using to get those numbers?

[johnt]

Sober,

The sites used were www. rockauto. com and www. acdelco. com
They were posted earlier in this thread.

Thanks John, I thought so but just checking to be sure.

[GreatWhite496]

Doug, with these rotor fit 17" wheels? I am planning a brake job and some other things for the end of March when my 3 child gets here. I figure I will take off of work for a week, and I can drive the wife's Suburban...allowing me about a week of down time on the AV....I have a 2500 so I would imagine the parts numbers and all are different. Just trying to do my research now.

I plan on one day going up to a 20" wheel, I just can't do a brake upgrade and new wheels and tires at once.

[DougD]

Stock sized rotors, I still run my stock wheels.

Should even work with a 16" wheel.

[MS03 2500]

The part number for the 2500 are on page 5 Jimbo did his.

[GreatWhite496]

Thanks both of you...I'll admit to not reading 7 pages to find it...hopefully it will help me to pull the reins in on this beast when stopping

[MS03 2500]

No one reads 7 pages I just remembered because he posted them for me. 

[jimbo53188]

yup i did this, stock 16' wheels, part#'s are in prior posts.   durastop #'s for a 2500, front's  PADS 17D784CH , ROTORS  18A1642,18A1643.   rears's PADS 17D785CH , ROTORS 18A1640,18A1641.  i realized i had'nt posted the durastop #'s

[ramv]

Any durability reports?  I am a little worried about cross drilled rotors...

[ramv]

Aw hell, I will find out for myself.   

$313 with shipping for pads and rotors for the front with the 897583795983 rock autodiscount code.

I was getting vibes empty coming down the mtn last time from Moab and got caught in Ski traffic, we will see if this helps.....

For running at combined weights of over 19k lb, I think it will be a good test.

[DougD]

Any durability reports?  I am a little worried about cross drilled rotors...

Having put over 80K on these same rotors on my Impala, no issues.

[ramv]

 

I had smoked them badly coming into Dillon a year or so ago and was getting some bad vibes when they got hot.

Next to the neighbours EXT


Pads were cracked


Look good...


Overall a very easy mod.  First impressions are mild,  they work fine, feel the same as before, but once they break in, it should be interesting.

I used an 18 mm, 20 mm (wrench and socket), 1/2" ratchet and breaker bar (Ran out of CO2 so no impact), a 10 mm to remove the brake line clips so I could set the caliper on the ground (have dropped them in the past working on trail repairs).  Took me a couple of hours, not bad for a parking lot break job.  A lot quicker then taking it somewhere.

[Z66 BUTCH]

Can someone comment on the 325/330 nightmare? I remember going through this when I replaced my rear rotors the first time.  The rotors I had to go with appeared thicker (wider vent), but I don't remember if they were 325 or 330.  Is there a rhyme or reason to this, based on VIN?

I'd like to do this upgrade since it's time for new brakes, and would obviously like to get the right rotors the first time. 

BTW, this is a great site.  I've been lurking for about a week and picked up a bunch of tips on things that were bugging me about the AV.

John

Many believe, myself included, that Z66/Z71 gives you the bigger rotors.

Honestly, the best solution I know of is a visit to a dealer with your VIN to be sure, OR removing a rear rotor and measuring it.  Thickness and diameter are different - not just the diameter.

I believe the answer is that the 330mm rotors go on the rear ends that have a locker and the 325's go on all on all others. I will not bet the farm but it seems this way to me.........thoughts?

That would follow with Z66/Z71 having them, certainly.

[Z66 BUTCH]

And may explain why some others have the larger ones while some don't.............

[soda7o]

went and priced all the parts but rock auto wanted to charge me almost 300 for shipping... WTF?

[DougD]

It is kinda heavy stuff.

Take the prices and see if a local dealer will match or come close.

Tim to resurrect Doug's thread here.

I have an 05 Avalanche Z71, and I THINK I've got the P/N's right now.

Note: AC Delco prices lower for the front pads.

Any issue with mixing rotor/pads by brand?  I wouldn't think so.

I'm still not sure if I'd be doing the rear brakes.  Any noticeable gain by doing the rears?

[avboy]

hi guy, a quick question.  gm improved the brakes for the 03 and later years.  do the same part numbers work on an 02?  would this mod have better results on an 02?

thanks

[DougD]

Your best bet would be to go to acdelco.com to confirm the part numbers.

[nfhjr]

Just replaced the front rotors on my 02 Z71 with napa parts the front rotors were $115 each and the pads were $90 can wait to replace the rears as truck passed PA Inspection and will order the rears after the Holidays when it warms up, measured the rear rotors at 330 mil and am replacing the park brake setup at same time.

[larrygto]

That would follow with Z66/Z71 having them, certainly.

Following this logic I bought 320's as I have a plain old 1500 and of course when I took the rear wheel off  I see 330's?

[Z66 BUTCH]

Following this logic I bought 320's as I have a plain old 1500 and of course when I took the rear wheel off  I see 330's?

Does your Avalanche have a locker rear axle? It will have a code: G80 on the glove box door.........if so the logic is still in tact:

I believe the answer is that the 330mm rotors go on the rear ends that have a locker and the 325's go on all on all others. I will not bet the farm but it seems this way to me.........thoughts?

[larrygto]

Yes it does, I thought the lockers only came with special packages?

[Z66 BUTCH]

Yes it does, I thought the lockers only came with special packages?

Nope, the locker can/could be ordered by itself but did come in the Z66 and the Z71 packages.

[Sealteam1]

DougD,
 How many miles do you have on you durastop brakes now? Any issues? Any noises and is there a lot of dust? Have you noticed any downside to the upgrade? Has the braking stayed the same, gotten better or gotten worse? Sorry to sound like a survey but Im trying to get more long term info before I do the upgrade otherwise Im just going to get a set of stock gm parts. 

[DougD]

Over 30k thus far, the dusting is much less than factory pads (although my wheels are also coated which helps shed the dust), no change in braking.

[05HrlyHlr]

Hmm I think I need some new brakes now!!! 

[hlj1215]

awesome post i did my brake pads after reading this..

[Big L]

Was going to replace the ole lady's Tahoe with Napa parts when I remembered this thread.  They don't offer cross drilled or slotted for the 07 yet so, I went with the Durastops front and rear (370 front rotors and pads with rear pads) was going to turn the fronts but with hair line cracks (Jerry at Sosebee Automotives said that they would be too weak and wouldn't turn them), just told her we would be better off replacing them.  07 Tahoe LTZ with 75k she hauls around a lot of stuff for work and travels frequently through out the month.  Thanks Doug and all for the posts.

[wannamess?]

do you think this mod is attemptable by someone who has never done a brake job before?

also are the raybestos and durastops the same or is there a difference?
thanks for putting up with my stupid questions

[DougD]

In reverse order - yes, they are the same - same manufacturer, different box.

Never done brakes, don't try it.  Start simple

[wannamess?]

does it matter which one i get then? would midas put in these kind of brakes?

[funk_drum]

I hope to do this by the fall.  But I already have some other mods waiting for me.  Shocks, new keys, audio, and some little things.

[DougD]

Ask them.  Every location is different.  Most likely won't install "customer provided parts"

[gilkman]

ordered mine today.  looking forward to improved braking.   

[gilkman]

Fedex delivered today!  got a project for the weekend!

[Sirshopolot]

Thanks for the write up and review 

Getting close to brake replacement.

[Sirshopolot]

Called and got the part #'s for an '04 Z71

Will start shopping for price 

[gilkman]

Installed over the weekend.  initial reaction is that it is firmer and stops faster. 
for those who  installed, did you do any kind of break in manuvers, such as several hard 60-0 stops?
thanks,
Jim

I did. I ended up with a dark layer on the rotors and it worked just as I was told that it would, much better stopping. I don't remember the routine, it seems like it was progressive with harder stops and shorter cool off times?

Mine have been on for several thousand miles, I wonder if I can do the same thing again and put a layer on the rotor to improve stopping again........it does not seem as good as when I did the install but I know they are not wore out yet.

[Sirshopolot]

gilkman, did you go with the ACDelco Durastop drilled and slotted rotors and ceramic pads?  If so, can I ask what the total was?

[gilkman]

I actually went with the Raybestos setup.  $286 total for the fronts.

[DougD]

The Raybestos ones that are the same as the Durastops?  Since Raybestos makes them, apparently

[gilkman]

That is my understanding after reading through this post.  The rotors look the same as pics posted.  Pads are ceramic and come with sliders and silicone lube.

I think that you will be shocked how much better your Avalanche will stop after this upgrade! All brake pads have to be bedded-in with the rotors. Read up about burnishing the new brakes, I did it and boy did they stop great!

Thanks Butch.  I hope so. 

I was going to search that.  Never heard of it except here.  Do you have a link to the instructions?

[Z66 BUTCH]

I think that I followed the instructions here:

http://www.zeckhausen.com/bedding_in_brakes.htm

Maybe I modified it, seems like I worked my way up to the 60 mph stops by starting from 30, then 40 then 50 etc. Don't over do it or get them hotter than recommended...........when done make sure the brakes are cool before coming to a compleat stop or else you could end up with some pad transfer on the rotor that will give a shake when braking much like a warped rotor. When you are done you should see some of that transfer on the rotor but it will be smooth all the way around, this is what helps with the braking....

[Sirshopolot]

Thanks Butch.  I'll check it out 

[Sirshopolot]

Well I guess we got the rotors and pads replaced just in time

This is the right rear that went metal to metal without warning.

The rotor is a little thin and not much left of the pad 

[Sirshopolot]

Here are the new Raybestos Advanced Technology drilled & slotted rotors and Advanced Technology pads

[Sirshopolot]

Here's the original rear rotor ....

[Sirshopolot]

Here is the new rear Raybestos Advanced Technology rotor ......

And the old and new rear rotors side by side

The Raybestos rotor is narrower because It's the wrong rotor for my Av.

After allot of time on the phone arguing with customer support (and I mean allot) I had to purchase new rear rotors and pads then wait just over 3 weeks for a refund.

[Sirshopolot]

Here's the original front rotors .....

[Sirshopolot]

Here's the new front Raybestos Advanced Technology rotors .....

[Sirshopolot]

Heres the original and new front rotors side by side

And the finished look 

So far they seam to be allot better at stopping the Av although it's hard to tell as we had to drive metal to metal for 2 weeks, so anything would be better at stopping.  We like them so far.

Thanks for the original write up DougD 

[SpottyJ]

Nice job, thanks for the pics 

Question, how difficult do you think the job was (any comparison?)  Do you experience working on brakes?  I am contemplating doing myself, but have never worked on brakes before.

TIA

The last brake job I done was on my first car 24 years ago, so I had a buddy who helped.  Afterwards, I fully believe I could complete it on my own.  I would recommend getting some info from your parts store on the basics.  In my opinion someone with basic mechanical skill/aptitude can replace the brake pads on their Av with some basic hand tools.

JACKSTANDS!!!!!!

Thats a good point.  You'll need a good jack capable of lifting the 6,000+ pound Av high enough to remove the tires and a pair of jack stands.  Mine were placed just behind the wheel openings, under the frame rails.

Didn't see them in the pics, just the jack, hence my statement of concern

[enomehjashik]

does this upgrade not apply to 07 AV?

if so what would be the part #s.

07+ are different, so you'd need to research what part numbers you need.  acdelco.com

[butterfingarz]

ok replacing the rears pads should I go with the durastop golds or the gold cmax's? There both ceramic and 20 dollar difference.

also if I need to take both my rear rotors off and leave the avy like that for the night where should i put my jack stands to support the rear end? Im guessing before the trailing arm on the frame in the rear or can i put them under the axle?

[Jett1]

What did they say to sell for the difference in price?  When it is comparable parts it is really up to you. 

also if I need to take both my rear rotors off and leave the avy like that for the night where should i put my jack stands to support the rear end? Im guessing before the trailing arm on the frame in the rear or can i put them under the axle?

I would leave the stands under the frame rails so the axle will hang lower giving you more room to work on the breaks.  But if you want them under the axle you can.  If you have asphalt driveway put some wood under the stands or they may sink in the asphalt.

Good luck

Heres what I ordered:

Raybestos Advanced Technology Drilled and Slotted Front Rotors
PN - 56825PL (Front Left)
PN - 56825PR (Front Right)

AC Delco DuraStop Drilled and Slotted Rear Rotors

PN - 18A1787 (Right Rear)

and Raybestos Advanced Technology Ceramic Pads
PN - ATD785C (Front)
PN - ATD834C (Rear)

I had to go with the AC Delco rears because they were out of the Raybestos rotors. 
This has taken over a month to resolve.  I will post the outcome when I hear from RockAuto after they receive the return.

What ever you do, double and triple check the part number of your rear rotors for your Avalanche!

[gn85]

I just bought my front rotors and pads from rockauto.  I got exactly what I needed. 

I'm really pleased with the Raybestos brakes.  I must have got the last ones they had.

[erickpl]

The confusing part is that Rockauto lists 56825PL AND a 56258PL part number.  The first is 95.79 and the second is 130.79.  Wanting to confirm that 56825PL and PR are the correct ones for an 05 Z71 WBH.

ARGH!

So many numbers, so few clues.

Did anybody do a brake fluid flush at the same time they did all this?  After watching Trucks! this past weekend, seeing that NASTY brake fluid, it has me wanting to do the flush too!

It has nothing to do with a WBH or cladded, what it does have to do with is if you have a locker rear differential.  Look in your glove box, if there is a G80 code then you will need the larger, more expensive rear rotors, I DON'T KNOW ABOUT PART NUMBERS..... the fronts on all 1500's are the same. This is the best information that I can figure out and so far it has worked for everyone!

I'll definitely be keeping it in mind when I get to the rear brakes.  They are looking about brand new.  The durastops will be replacing some warped and pulsating front rotors/pads.  So I have the time on the rears for now.

[butterfingarz]

Going to pick some pads up at autozone this weekend they have the duralast gold's and the gold max's only difference from what I can read are the max's are "ultra quiet" both are ceramic. 20 dollar difference between the two.

It has nothing to do with a WBH or cladded, what it does have to do with is if you have a locker rear differential.  Look in your glove box, if there is a G80 code then you will need the larger, more expensive rear rotors, I DON'T KNOW ABOUT PART NUMBERS..... the fronts on all 1500's are the same. This is the best information that I can figure out and so far it has worked for everyone!

Butch is the one who saved me after getting the wrong rear rotors.

Thanks Butch!!

You are welcome, did you get the correct rotors on and do you feel a difference in the stopping power?

[Sirshopolot]

Yes, got the correct ones.  Received credit for one rotor so far, waiting to see if they post the refund for the other rotor and the pads on Monday.

Definitely tell a difference between the wrong ones and the correct ones.

Anyone know what the difference between the:

Raybestos ATD785C Front; Ceramic; Originally Equipped With Ceramic; Contains Hardware $72.89

And the:

Raybestos ATD785P Front; Ceramic; Originally Equipped With Ceramic; Quiet On Arrival Friction Technology; Contains Hardware $49.79   



Thanks!

$20-odd  bucks

[intensem1rider]

haha, I guess I should call Raybestos then.

[maverick1974]

I think one number might replace the other.  I think I saw that stated on a vendors website, not sure if it was rock auto or another.

the part # ending with "p" are police pursuit pads, DO NOT order these! they stop great but eat the rotors and only last about 20 thousand miles

[intensem1rider]

Bingo, just what I was looking for!  Thanks for the tip to stay away from the "p" pads.

Got the rears in on my 03 Z71 this weekend. The only difference on mine was to take the calipers off, I needed a 12mm socket and a 5/8 in wrench instead of what Doug posted. i got the Raybestos ones too.

Did the rear pads and rotors in the driveway couple weekends ago. Went with the duralast goldmax ceramics. Also duralast rotors. Slightly better braking but I'm sure just replacing worn pads and rotors will do that not the product. Pretty cheap too. 40 i think for rotors and 60 something for the pads. Saved $200 or more easily for dealership to do it.

Just FYI, Duralast is Autozone, Durastop isn't, and MUCH better

Been digging around RockAuto and ACDelco sites, but cannot find the drilled & slotted rotors for 07+ models.
Anyone have part numbers for AC Delco / Raybestos for the 07+s?

[Web]

Got the front ones in today.... what a waste        Have 119000 miles on the original set, and still had plenty of pad left... no grooves...I changed them about 20 thousand miles too soon...        

They feel a lot better...

[Denman]

Check out Royalty Rotors they are American made out of California and they have a lifetime warranty, just Google it for distributors and company information. If your going to spend the money on brakes take into consideration how long you are going to keep the Vehicle, it works for some but not others because of the cost involved. Awesome thread full of excellent brake information and pics...top notch.

[xceebeex]

How much of the front does the braking in the Avy? I think I may have warped rotors because my steering wheel vibrates when hitting the brakes at higher speeds so I am thinking of upgrading the brakes while I am at it. I only have about 57k miles on it so I don't really think the rears are that bad so I am thinking of just replacing the fronts.

I guess what I am getting at is if I put the upgraded brakes on the front and maybe never upgrade the brakes in the back will I see a big enough difference to warrant the extra cost?

[xceebeex]

Anyone?

[ygmn]

Rear brakes tend to wear out faster which would lead one to beleive they do more of the braking.... but..

if you upgrade the front brakes you should upgrade the rear to ensure a balanced setup...

Interesting, I have never had a vehicle where the back brakes wear out faster. I wonder if that pads are smaller in the rear which makes it appear they wear quicker.

Anyway, I don't really want to spend a ton of money upgrading my brakes right now, but like I mentioned, the rotors seemed to be warped in the front because of some steering wheel and brake pedal pulsing that I am getting. So I am not even sure if the back brakes are that bad.

[ygmn]

put stock type rotors on front then.... maybe?

check problem brake section for threads on rear pads wearing out first...

Ok, thanks, I will check that out.

[Z66 BUTCH]

My opinion is that the rears wear out faster because of two things.....they tend to stick and drag more than the fronts for some  reason and they are smaller pads. Years ago the fronts would ware out first so I guess they made the rears smaller and now they wear......I am guessing hat the fronts still do most of the work.

[DougD]

Typically, your front brakes are the harder working ones.  I believe the brake bias in the Avalanche is overcompensated to the rear in an effort to balance the braking a bit better, thus contributing to the rear wear being accellerated in many cases.

Looking at the Rockauto site, I'm not seeing the P/N's below:

ST56825L - Super Stop / Drilled and Slotted (left)
ST56825R - Super Stop / Drilled and Slotted (right)

I did find ATD785C - ceramic pads.

Have the part numbers changed?  Doing a search for 56825* I find 56825R but no 56825L ... no ST in front.

EDIT: Okay, brain fart.  Those above are the old numbers, as pointed out a while back...

The 56825 PL and PR are the ones I'm needing.  I was thinking about the pads with the P in them thinking they were the police version.

So the list to order today would be:
56825PL
56825PR
ATD785C

With discount code, I paid 254.00   WOOT!

Looking forward to doing this and painting the calipers!

My bad I see his cost is for front only.

[gilkman]

I have had the Raybestos version of the durastop on for several months now and thought I would provide some feedback.
I did several break in runs (progressively firmer 60-0 stops) and then drove the avy normally.  the first month or so, the pedal felt better than the stock,
but not significantly better.  within the last month, the pedal has a firmer feel, so I guess there is some break in period required.
not very scientific feedback, but I am pleased with the performance now.

If you do a search for rockauto discount code, it is easy to find one.

Right now, I'll be happy to get rid of the pulsation from the warped rotors/pads.

For those that have done both front and rear, did you do them at the same time or wait a bit for the back?  If you waited, how was the improvement once you did the rear brakes?  My immediate problem is the front, but curious to see if it is justified in the gains vs doing the back at some point.  As mentioned previously, the pads still look new (VERY little wear on them at all).

UPDATE:  I ordered these on Tuesday afternoon.  Paid for basic shipping (UPS I thought).  Thursday afternoon, they were on my front porch, shipped FedEX!!!  Verified all the part numbers, opened and inspected.  Looks like I'm ready to go!!!







SEXY!!!

Now a quick (STUPID) question.  Brake rotors labeled R go on the passenger side, correct?  I can never remember if it is the right side as you sit in the seat or as you look at it from the front...

[erickpl]

Got them done.  Those pads go on the Chevy truck calipers rather weirdly.  Not that they were that hard, but they were more confusing than any brakes I've ever done, and that includes brakes from VW, Audi, BMW, and Pontiac.

Meh, got them done, but also painted em.  Here they are.









While they look orange, they are a nice bright red.  Initial impressions have the pulsation gone and I bedded them gradually up to 60-0 stops.  I'm sure they'll grab a bit better as I drive it more.  But braking feel is more linear and smooth than it was before.  As posted above, it is likely one of those things that gets a bit better once the pads are fully bedded.

[Dad's Tonka]

Ok, I really want to do this Durastop upgrade but have been repeatedly told that ceramic brakes are not good for towing.  My 2500 is useed 90% of the time for towing.  Suggestions please....really tired of the poor braking of the truck and need to know options/reviews especially if you are towing.

Thanks,

Paul

[ygmn]

Ceramic brakes are stock I beleive
hence low dust and squeel

[mleeber]

What the heck...I just picked up some DuraStop pads at the local Chevy dealer where I have an account setup as a jobber and my cost on the pads was $77. The retail for $85. I checked the prices on the rotors and they were over $200. Is this dealer priced out of line or has the price more than doubled since this thread started? Anyone know the part number for the Raybestos rotors for the rear on an '06 Z71?  Oh, the other thing that surprised me was that the rotor for one side is about $18 more than the other....

Thanks!

raybestos part #'s for 06' z71
front pads = ATD785C
rear pads  = ATD834C
front rotors = 56825PR & 56825PL
rear rotors  = 580165PR & 580165PL

[mleeber]

Thanks Jimbo!

[butterfingarz]

Had the Durastop Gold Ceramics on for a bit now and they definitely cause more dust than the AC Delco's they replaced with little to no difference in braking performance.  If I would do it again I would save your money, not worth it.
