Six problems related to brake disc have been reported for the 2000 GMC Sierra. The most recently reported issues are listed below.
Vehicle brakes damaged by road salt corrosion, causing rear brake calipers to seize up and brake disks to delaminate. Rear brakes were completely inoperable.
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.
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.
