2000 GMC Sierra 3500 Brakes Problems

“Tried to stop on dry pavement, but due to ABS malfunction, the truck wasn't able to stop. We have had many incidents where there could have been property damage and possible death due to braking system. The ABS would calculate wheel lock up even when the truck did not have lock up and engage system not allowing truck to stop. Mailman pulled out in front of truck couldn't slow down, but did avoid accident. Ran a stop sign once. Almost ran into the side of a building. There are a number of incident's, I know of three or more vehicles with same problems, all are made by GM. …”

“2000 Gmc k3500 reg. Cab pickup 4x4 -- brake pedal goes to floor and ABS system engages. Vehicle has extended braking distances on dry pavement. Brake light comes on and goes off after re-application of brakes by pumping them. Pedal also goes to floor without engagement of ABS system and vehicle will not stop. Problem has been recurring for three (3) years but this time vehicle was intentionally driven into a snowbank to prevent a collision with another vehicle. …”

“Steel brake pipe that carries fluid to the rear brakes ruptured next to the fuel tank. Fluid is leaking and pooling on the flange of frame. Stopping performance is degraded, and no warning has registered via the instrument cluster or idiot lights. Line is badly corroded, which perhaps is to be expected given the age of the vehicle. However, I find it ironic that the exhaust system is made of stainless steel yet the brake lines are not. This vehicle has had other brake-related failures that GM refused to correct, despite having recalled contemporary vehicles with identical problems. …”

“Abs brakes activate inappropriately at low speeds (under 10 MPH) on smooth dry surfaces. This lengthens the stopping distance and creates the potential for a crash when available stopping distance is limited. The design is flawed in that 1) normal corrosion, expected during the life of the vehicle, frequently leads to this failure of the brake system, and 2) when this normal, expected corrosion occurs, the ABS system does not 'fail to safe', but instead fails in a manner that reduces brake system performance and increases stopping distance once problem began, it happens all the time. …”

“While applying the brakes a loud noise was heard from the front. Consumer drove the vehicle to the dealer for inspection, and mechanic determined that the brake pads needed to be replaced. Mechanic was waiting for conformation approval to replace the brakes pads. Consumer contacted the dealer more than once, and the problem recurred.”
