I just found out that GM is doing what they refer to in the business as a 'Silent Recall' on the parking/emergency brakes on the '02 Av. I was hearing a noise constantly in the brakes even while driving. The noise turned into a grind and I took it into service immediately. A mechanic that was working on my Av told me that Chevy has a whole re-build on the system and he just found out about it in a "Service Bulletin" ie: Silent Recall. This thing is 1 1/2 yrs old with only 28K miles. I need a completely new rotor for the pax. rear. That's bad enough by itself but it gets worse. Turns out after talking to some other Av owners in the area that we are all experiencing another brake problem. It appears that the calipers are getting hung up and wearing the inboard brake pads out causing early pad replacement. Who ever heard of replacing rear brake pads at 28K miles? For that matter who ever heard of replacing rears before fronts? This service manager expects me to believe that this is somehow my fault. After telling other Av owners of the brake issues, they report similiar problems with the inboard brake pads wearing out on all four wheels. One guy said his dealer would only agree to cover the rear because the fronts were normal wear. Yeah right on the inboard pads only it's considered normal wear. So I guess if you take two outboard pads that are still good you only have to buy one set of new pads. I know how 'bout if we take the service managers car and only remove half of his brake pads. When he wrecks his car we can see if he still thinks it's normal. So far this has only been a problem for me on the rear wheels. My front pads look brand new still. Anyhow I am just curious to see how many others have experienced this problem. Thanx.
