Three problems related to brake disc caliper have been reported for the 1996 GMC Jimmy. The most recently reported issues are listed below.
Pulled out of parking lot on to road. Applied brakes while approaching a light. Even with both feet on the brake pedal the 1996 GMC Jimmy barely came to a stop from a distance of 6 car lengths going 30 mph. Narrowly avoided rear-ending vehicle in front of me. This was not the first time but the closet encounter. Before this incident I had the front rotors, disk pads, calipers, front flex lines, booster, vacumm hose and connector on engine to booster, master cyl. , and rear brake linings - replaced. Since then I had the vacumm checked from the engine to the booster and was told the booster was bad. I had the booster and masterc replaced again. Still no change. Pedal goes too far down and feels like it hits a brick followed by very weak breaking action.
Brake caliper froze/stuck, causing wearing of pads and rotors.
Brake calipers are causing premature wear of pads and rotors, replaced calipers however continue to wear unevenly.
