Brakes..ugh...help.
Put a power booster on a '71 Super Cheyenne...had nothing but trouble since.
Brand new Booster and Master, new rotors and lines...had the issue that the brake pedal wasn't returning all the way back and they were sticking on unless you lifted the pedal back with your foot.
Bled and re-bled everything, adjusted rod length, checked the master cylinder spring...nothing. Returns fine when the engine's not running, but stops about 1 1/2" shy of normal when you fire her up.
Hated to do it but tried the band-aid method of hooking up a spring to the pedal so she returns perfectly...woohoo!! Took her out for a test drive and wow...great stopping truck!! Then 15 minutes in the brakes start locking up again..ugh. Got to the point that they got so hot had to pull over and let her cool down..they were holding so much it was hard to even move....but as soon as she cooled down she worked fine again.
Have seen many, many GM threads where the pedal only comes back partially, but nobody ever seems to post the fix when they find it (or hasn't it been found?).
At wits end here...any suggestions?
