Brake Disc Problems of GMC Sierra

Vehicle brakes damaged by road salt corrosion, causing rear brake calipers to seize up and brake disks to delaminate. Rear brakes were completely inoperable.

Vehicle is parked for extended period of time (2+ weeks) and the machined surface on the rear rotors rusts and peals off leaving a rough surface wearing out pads prematurely and necessitating the replacement of the rotors.

While applying the brakes the pedal went to floor. Driver noticed that the pedal was hard, and vehicle would stop on its own. Driver took vehicle to the dealer for inspection, and mechanic determined that disc brakes and power booster needed to be replaced.

Consumer heard something pop ping and fell into the street. Consumer had no brakes in the rear. In the front the brake disc was badly pitted because of the poor quality of alloy. Consumer was driving up to a stop, trying stop, when the brakes failed. Consumer sailed on through the stop sign. The front brakes were grinding due to the metal on the disc. The consumer had to replace with a whole new braking system with aftermarket products. Consumer did not feel safe with the gm brakes. This happened all of a sudden, there were no prior problems. This vehicle only has 8,000 miles on it. This happened while slowing down between 10 and 15 mph.

My 2000 GMC Sierra 1500 pick up has had poor braking from the time I bought it new from the dealer. They said it was normal for this vehicle. While driving to wisconsin from our ohio home on July 1, 2004, I had to brake quickly due to heavy traffic going through downtown chicago. The brakes did not totally fail, but were poor enough that I had to quickly change to the next lane to avoid hitting the vehicle in front of me. After returning from vacation, I did some investigation online and found through a friend of a friend that gm engineers were aware of brake problems with this and subsequent models and instituted a fix with the 2003 model to correct the problem. I then contacted my local dealer, who said gm had no recall nor would they cover any repair costs incurred, since I was 3 months out of warranty even though within the mileage. I had the brakes repaired at the dealer, norris GMC in medina, ohio, and it totaled $1,587, or close to that. I found that to be preposterous and filed a complaint with gm customer service. To date, they have offered no retribution for this claim. Knowing that they had a problem, which was subsequently fixed on later models is reprehensible to me and I feel they should have at least notified owners to have their vehicles inspected when they learned of the defect. I doubt that I am alone in this issue and would like your assistance in bringing gm to offer some retribution for those of us who have had similar experiences.

Brake problem w/2001 GMC Sierra. Four wheel disc brakes. Rotors were complelely rusted at 60k miles. Severe loss of brake power although pads were not ignificantly worn. This caused replacement of 4 rotors. Gm mechanic said this is common problem.

At low speeds abs brakes grab and don't stop vehicle when brakes are applied. Contacted dealer. All four disc brakes are flaking apart.

When applying brake at low speed in wet weather there is a grinding noise. Dealer cannot find a cause.

Rear disc brakes are of such design that they get wet and rust, which causes them to drag. Rotors wear out prematurely due to this, causing extended braking distance.

When having to make a sudden stop brake pedal will notdepress. Then, upon hitting it again , there was vibration. On rough roads it was impossible to stop. Might as well not had any brakes.

Brake design is inadequate for size of vehicle, one ton 4wd truck also most 3/4 suburbans and trucks have the same problem. In the past the truck has pull hard left across the road with no prior warning, brake pads are required to be replaced depending on pads every 5000-10000 miles. This truck has been in under warranty three times to replace pads, once to replace rotors, once to rebuild calipers, and once to replace rear drums with 21000 miles on the vehicle. It appears that normal passenger design size brakes were used on a light truck and that the proportioning between front and rear utilize the rear brakes very little. This brake life is with out any towing or heavy hauling. Given the life which is abnormally low, during steep mountian driving on a long trip the front pads could fail without warning and the front appears to be doing all the braking on under designed size pads. Why else will the 2000 models crew cab 4wd have hugh 4 wheel disc brake setups?? gm has done nothing to retrofit or resolve issues except replace parts over and over, reference gm file # 99063603. . . Thanks in advance for any assistance you can provide.

I have experienced excessive wearing of the front brakes, which has resulted in the rotors being replaced first, then the pads replaced 2 weeks later, and upon replacing the pads the new rotors required resurfacing. Since then after driving approx 5k miles, I was told that the new pads are appox 40% worn. I required the right front balljoint to be replaced when the rotors were done. When applying the brakes & hitting a bump in the road, the brake pedal goes down to the floor and has a complete lose of braking. It failed the annual inspection, due to a leaking donnut gasket. The tailgate squeaks & rattles, and appears out of alignment. The front driver's door creaks requiring repeated greasing. There appears to be excessive wearing in the front end and braking system, as well as excessive creaking & noise from the rear area of the truck, tailgate, and driver's door. I have been met with continued resistance and lack of answers from both the mfg and dealer. Any help or information would be appreciated.

When driving vehicle it drives very rough, meaning the vehilce vibrates and shakes consumer took the vehicle to the dealership, and they replaced the rotors/pads and shoes, rear axle, and hubs. But vehicle still shakes.

On repeated times braking at lights and stop signs with an rough road surface the rear tires will skip, the abs system will buzz, the brake pedal will go down below the pressure I am applying and it feels like the truck will not stop. Once the truck has stopped the brake pedal is on the floor. When released it slowly comes back up. When accelerating away from this stop, it feels like the brakes are still applied. I have learned after many times of this happening I have to stop the truck, back up a bit and I can feel them release. I can drive normally then. When this happens, it is a intermittent problem, and I have reached my destination I can smell the brakes in the front as if they have been applied while driving. The rotors are now blue and the pads are now worn down to less than 30% of factory thickness. The dealer on three occasions has said they can not duplicate this problem. It is my driving habits on the brake wear and is common for this model to wear brakes like this at this mileage. I also can not stop this vehicle on a panic stop situation. Last month I had to stop the vehicle in a panic at 2-3 mph. I hit the brakes, the vehicle nosed down, the abs buzzed and the truck continued to roll into the car in front of me. The brake pedal was on the floor with no further travel left. I was standing on the pedal pulling up on the steering wheel and the truck would not stop. The next morning I took it back to the selling dealer durant autoplex. I could demonstrate this condition as could the service manager. He said this is not uncommon for this vehicle. He even said his demo was worse than mine. I filed a complaint with him and GMC. I had my truck fixed and ron bayers the service manager said he had the abs system check and double checked and found no fault with any component in the abs system. He said there have been many complaints from owners with similar vehicle that can not stop them under a panic stop even at hwy speeds. What do I do? please advise.

Seats->drivers and passengers seats (leather) cracked in less than three years. Expected more for the price of this option. Have had brakes replaced 1 - 1 1/2 months prior to failure. I was out in the back country, 40 miles from paved roads, when I heard the rotors being torn up by what was left of the brake pads. It ruined both rotors. I was told at an independant shop that the calipers failed. I went to the dealer and the service advisor insisted that the calipers didn't fail . It was just cheap brake pads. I know for a fact that wasn't the case.

Brake pads overlap the rotors, part of the pads are missing from the rotors, also, missed part of the rotors. Brakes make loud noise. The pads and rotors have been replaced and dealer. Cannot duplicate the problem.

Back brakes are not functioning properly, causing the front brakes to wear out excessively. The front brakes have been replaced twice. Dealer has been notified.

Abs brake problems: when going over a bump and applying brakes, they chatter and become mushy. This extends stopping distance which may cause a crash. This mostly happens first thing in the morning. Truck has been to the dealership numerous times. Dealership stated that this was a normal condition. Front disc brakes have been replaced, but there still was a problem with the brakes. This has been an ongoing problem for over a year.
