Vehicle had severe symptoms of needing brake replacement at 32,000 miles (rears) and again at 42,000 miles (fronts). A burning smell coupled with very hot brake components and severe pedal pulsation was noticed. When repairs were done the brakes were found to be prematurely worn out and all parts showed unusually severe rust damage. The brake rotors were delaminated and falling apart. The rear backing plates, which usually last the life of the vehicle, had holes rusted through them. The valves were so rusted that they no longer can be used to bleed the old fluid out and will eventually cause an internal rust condition that can cause brake failure. In addition, on a vehicle that had inadequate brakes to begin with, a large portion of the rotor surfaces was not even being contacted by the brake pad. This caused an unsafe condition which drastically increased the stopping distance of this vehicle. New parts were installed and the old parts are available.

The contact stated while coming to a stop she depressed the brakes and the pedal went to the floor. She noticed brake fluid all over the road. The dealer told the manufacturer the brake lines were completely rusted. The rotors have been turned once due to accumulation of rust. The dealer told her the recall 05v379000 did not have anything to do with the brake system, just the sensor. Also, the dealer told her that because she did not have an established relationship, did not show loyalty to a specific dealer, and was not a current customer of GMC, they could not fix the vehicle under warranty.

The brake rotors are warping. There is rusting in the brake area. The consumer first noticed the problem on September 10, 2005. The consumer had the rotors cut to take off the bad metal. There have been no accidents.

The contact states had recall work completed, and the dealer discovered the rotors were severely corroded, and the brake pads needed to be replaced. The recall work was completed under NHTSA recall campaign 05v379000, concerning the anti-lock brakes. The service dealer suggested the metal contained in the rotors was defective. While the dealer acknowledged the fact that rotors should have a life span of more than 14,000 miles they refused to offer a free replacement. Therefore, the rotors and brake pads have not been replaced. The contact felt the recall should be expanded to include replacement of the corroded rotors. Updated 09/05/07.

The contact states the abs system is bad. It almost caused an accident on 8-20-05 because brakes went to the floor. There was no braking power. Had to shift the car into park to get the vehicle to stop. The contact was going very slowly when this happened. This was the first incident of this kind. The dealer repaired the vehicle. They replaced the wheel bearings, the hub, the rotors, and a cable that was attached to the wheel bearing on 8-22-05. It seems to be fixed as of now.

2002 GMC Sierra. The consumer states the steering shaft bounced up and down, it was not correctly put in. This caused the front end bounce from the steering box to the steering wheel. This problem has been corrected, but the dealership stated they were having a lot of these problems. This has been happening since the purchase of the vehicle. The consumer thought the vehicle was out of alignment. Also, the rotors a had to be replaced because of the shaft bouncing up and down. The right tie rod was also replaced. The problem was constant with the vehicle.

Consumer stated brake failure resulted in extended stopping distance. Took to a dealer for this issue 3 times. Dealer's general manager said there was some type of problem but he did not know what caused it. No repairs or parts replaced. On oct 18, 2004 the rear rotors were turned. Even after the rotors were turned the brakes still performed poorly. The right fog light fell off while driving.

I had a deer jump in front of me and I hit the brakes hard and my truck barely slowed down. I avoided the animal. I then tore apart all brakes and found the rear extremaly rusted. I replaced all pads, had rotors re-surfaced. Rear rotors were barely salvigable after sandblasting. Truck has 30,000 miles. This is not acceptable.

I took my truck in for an oil change and the dealer told me that my truck (50,000 miles) needed new front rotors because mine were "DE-laminated" I asked how this could happen and the mechanic could not give me a clear answer. The gm assistance center told me that the dealership told them the reason for this was I refused some dealer recommended maintenance, although the dealership service manager said that was not the case. I spoke to a metalurgist and he stated the problem was most likely from the manufacturing process caused by not cooling the rotors properly after the were cast, since both rotors are only defective on the inside face. I also own a 1990 chevy truck with 270,000 miles that still has the original rotors. I am afraid this defect could cause an occurrence of brake failure and I am afraid to drive the truck under highway conditions. Also, after asking numerous others, no one (other than gm) has heard of this phenomenon.

2004 GMC Sierra pickup truck, notice brake problems at about 12,000 miles took truck to dealer to see what problem was, concerned was wearing brake rotors in front end, was told that rotors were defected from manufacturer thy were turned wrong at factory, they tried to correct problem by turning them at dealer problem returned at 30,000 miles, went back to dealer to correct problem then front rotors were replaced and rear rotors were turned also, again at about 34,000 miles problems with rear rotors occurred they refused to warranty them I feel that there's a wider problem then just a few truck and s. U. V. And a recall and a inspection should be done on all rotors from this year of manufacturing should be done for safety reasons I did save the rear rotors for measurement in the future if needed.

Consumer took vehicle to the dealer for a tire rotation, and was told that the rotors were eating up the brake pads. Dealership repaired the braking system by resurfacing the rotors and providing new pads. However, because of the steel being used the rotors will continue to eat up the pads, and this operation will need to be resolved every 10,000 miles. Manufacturer stated that the climate where consumer lived was the reason why the problem occurred.

Premature failure of rear brake system. At 48005 miles the entire rear brake system comprised of rotors and pads needed replacement due to deterioration.

Vehicle has 19000 miles on it and the brake rotors are badly scored and rusted, resulting in a pulsating brake pedal and the requirement of greater brake pedal pressure to stop the vehicle. The problem is primarily with the rear brakes, but the front brakes are starting to show the same signs. A recent brake inspection indicates that the brake pads are well within tolerance for wear, but the rotors will not pass pennsylvania state safety inspection in their current condition. I have consulted with at least four other individuals with similar vehicles that have encountered the same problem.

I purchased a 2000 GMC Sierra 9 months ago as a "GMC certified used vehicle" from a dealer with 33,000 miles on it. Now, at only 10,000(not hard) miles later,the front brake pads came apart & took chunks of metal out of both rotors,resulting in a $500. 00 front brake job(new rotors & pads). I don't think 10,000 miles is lot to ask from a set of pads & rotors,that the dealer's service dept said had 40% life left @ delivery.
