Sierra brakes won't release
 

I have a 96 Sierra 1500. Was having problems with the front brakes sticking especially on the passenger side. It wasn't very consistently though. Sometimes they worked and other times they didn't. So I replaced the pads, lines, calipers, rotors and wheel bearings (on both sides). I even put new wheels and tires on it. It did fine for the first few days and then it started doing the same thing. The brake pedal bearly goes down, I can smell brakes, again not consistently. What else could be the problem?

Have a shop do a flush. Might as well go ahead replace the master cylinder too. You may have alot of corrosion through the whole system.

I know I should have went ahead and replacedd the master cylinder when I had it apart. I did have a mechanic flush it, no results though. Someone suggested I check the ABS sensor. Do you know anything about that?

i'm having the same problem on my 04 Silverado 1500. Did you ever get it figured out?
