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.

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
