Old thread,but I am experiencing brake peddle fade all of a sudden on my 02 z71.
Don't use the truck often anymore and it was running fine before the issue started.
Went on a dump run with the misses last week and after a few stops noticed the peddle going to the floor and braking getting worse. I did top up my fluid as it seemed low. Made it barely to my destination and home with a very hard to stop truck. Pumping didnt do much, and the e brake didn't either.
Get home. Fluid level stays ok, start pumping in the driveway. With engine running, she goes to the floor and brakes barely work. Engine off, peddle gets stiff after two pumps.
No leaks anywhere to be seen.
Tonight I tried again, same thing. No loss of fluid. But no brakes.
Thought, maybe bleed her to be safe, but front bleed screw snaps off, and rear one strips the head.. Like I said, don't drive it much so its been a few years since she's needed brakes, or bleeding.
So, aside from needing to drill out my bleed screws and install new ones, thoughts on my root problem? How can you isolate vacuum boost issues vs master cylinder failure?
Thanks av lovers.
This is a new one for me. Never had a complete brake failure like this without obvious cause.
