I was going about 25 MPH when the truck ahead of me stopped. I hit the brake pedal hard and the brake pedal seemed hard as if it wasn't moving and my car just kept moving forward resulting in rear ending the truck ahead of me. I checked the brake fluid level after the car was towed home and the fluid level looked okay maybe down a little. Have never changed out the brake fluid and had the brakes recently checked by lew scwab tires brakes new brake shoes front and rear brakes okay
1995 Pontiac Bonneville experienced brake failure as a result of the rear wheel brake cylinders leaking. Erratic braking, swerving and the anti lock problems occurred due to the leakage. Both rear cylinders were leaking.
While driving 60 MPH the ABS braking system malfunctioned, causing the pedal to the floor which caused extended stopping distance, causing a severe accident. One person was injured in the accident.
When the brakes were applied under normal road conditions, they did not immediately respond, causing extended stopping distance and resulting in a collision at 55 MPH. Dealer was not notified.

Replaced master cylinder and rear wheel cylinders. Antilock brakes have always behaved strangely at times but have never failed to stop the car in a reasonable distance. 09/22/2001.

In addition the following no longer function or function improperly: fuel gauge does not work, refill based on mileage driven.

The problem started about 2 weeks ago, car took off and brakes were as hard as a rock, the only way to control car was to put in neutral. This last time I was on a freeway in southern calif. And the car took off again and I ended off the freeway in a vacant field to stop the car. I was afraid of going into a residental area. The first incident was reported and the car was checked out at a local GM dealership, and nothing was found. The car is there now again and they have found nothing. The car has an extended warranty and they have had it for 3 days.oddly enough when I called aaa to tow me out of the field this last time the dispatcher stated that her mom's Buick does the same thing. GM is making it sound like this is unheard of and they have no idea what is going on, yet on the internet there seems to be other cases.
I have had this car for just over 1 year, I have had to replace the front breaks 3 times and the rotors 2 times and the calipers 2 times, also the passenger rear wheel cylinder has had to be replaced 4 times and needs to be replaced again, also the drivers side wheel cylinder is in need of repair, all 4 doors will not unlock with the remote and the drivers door will not lock with remote, on third battery for this car and there is still a short somewhere causing a fluxation in the volt meter if the blinker is on, antilock break light will come on and off and breaks have failed several times and make a loud niose if slipping, also have had to replace spark plugs almost every other month and heater blower will come on and off at will.
Rear left wheel cylinder leaking and was replaced for a second time first time replaced at 19,725 miles, at that time both rear wheel cylinders were replaced under warranty (1/98), now on 9/27/00 the extended warranty only covers replaced the failed part, my concern is shouldn't they replace both wheel cylinders at the same time, especially from a safety perspective, the dealership and GM warranty people are telling me it's not necessary to replace both wheel cylinders, replacing one is OK and doesn't pose a threat for safety. Is this true and I am concerned that one wheel cyclinder became defective again only after 23000 miles were put on the car, this concerns me. Thanks
The body control module that works the door locks and windows. The clutch on the air conditioner. Replaced that then the compressor went out. The radio quit . Its had a roar in the rear end ever since we got it. They cannot find the problem. The gauges for heat , speed, rpms,oil, etc. Go back and forth when you start the engine then when they stop they don't read correctly. Speed doesn't read right. Master cyclinder went out 2 times.
Anti-lock breakes locked up while attempting to stop at a red light,the vehicle slid to the right and would not stop,and I slid through the red light.no accident or injuries occured.road conditions at the time were wet from a shower.
