I have a 2008 GMC Sierra 1500 and the brake
pedal will stick to the floor after pressing. I have to use my other foot to pull the pedal back. Put on a new master cylinder, bench bled, bled the lines and even tried a new booster check valve. Still sticking. Any ideas?
JA: Have you tried cleaning and oiling the brake pedal's pivot under the dash?
Customer: Yes, and releasing the the nut to the point if it is released any further it will come off.
JA: Are you fixing your Sierra 1500 yourself? What have you tried so far?
Customer: I have a GM certified, 25 year mechanic who lubed the pedal and said it needed a new master cylinder. Had another mechanic help me replace the master cylinder, bench bleed and line bleed.
JA: Anything else you want the mechanic to know before I connect you?
Customer: Nothing I can think of.
