After starting my vehicle with foot on the brake and putting the vehicle in gear it will move forward and occasionally roll for 4 or 5 feet before the brake engages. This is extremely dangerous as I'm pulling out of a parking space and merging with ongoing traffic !This has been going on for approximately three weeks. The vehicle literally has no brakes for four or five feet despite the fact that my foot being pressed all the way down on the brake pedal!! Last week I came very close to a major accident when I couldn't stop for an on oncoming car. Thank goodness the operator of the other vehicle stopped in time to avoid a serious accident! I immediately took the car to a local garage to have my brakes checked. They found no issues. I then took it to the Buick dealer, BICAL, and they found a serious issue. The brake vacuum pump had frozen and had actually disintegrated and no longer was functional. Parts from the pump entered the valve shaft area also. The end result was a $3,000 repair bill. The important issue here is the driver safety on the road.Although this was only occasional and at low speeds left unattended would lead to a total brake failure with major consequences and major fatalities!! God only know how many major accidents occurred with major consequences without anyone knowing the true source of the accident details. I have read online that 1996-1997 Cadillacs also have this same issue!! This is a very poor design and a major safety issue. After all there is no such thing as a minor brake issue!!! I'm avail to discuss this issue issue at your convenience. I can be reached on [XXX] [XXX] cell. Repair bill available.

Faulty brake vacuum pump. Leaking oil and vehicles brake pedal was stiff and luckily did not lead to an accident as I had to use all my weight to push the pedal down to stop the car. I took the car to a Buick dealership and they said the vacuum pump disintegrated while disassembling to put new vacuum pump in. This lead to parts of the vacuum pump entering the engine. There is now metal in the oil and engine is not running right with reduced power. Dealership said it is not their fault that GM made a vacuum pump that is notorious for falling apart into the engine. If the dealership is aware of a cheap part that often disintegrates into the engine how has this not been recalled? I see many cases online where this has happened. Dealership I took it to is vandevere Buick in akron Ohio. Jerry messenger is the manager that can verify my complaint.
