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.

When applying ABS brakes pedal went to the floor, causing extended stopping distance, nearly resulting in a collision. Consumer states he was advised that there was complete failure of the master cylinder ABS unit had to be replaced, and new front brakes.

Anti-lock brakes failed numerous times on off-ramp. Almost caused serious accident. Brakes pads, rotors and master cylinder replaced with no improvement. I contacted General Motors, they claim problem is caused by "stupid drivers".
