Uneven wear in the brake rotors. GM has redesigned the rotor because of this problem and the car has been in for servicing twice regarding this problem. Because car is now out of warranty, GM refuses to fix it even though they acknowledge it was incorrectly repaired previously and is a known problem. The uneven wear causes a shimmy in the car at freeway speeds. According to GM service bulletins, it generally happens after about 7000 miles from last brake servicing (as is the case with my car.

Have had the front rotors turned twice. Now the right front brake pad material seperated from the metal backing. Had to use transmission and emergency brake to stop the car. The braking system on these cars is total crap.

The rear rotors squeak when the brakes are pushed, a grove has developed in one of my rear rotors. Also, when I firmly apply the brakes the steering wheel vibrates. Dealer was notified and stated that pads and rotors are only warranteed for 12K/12months. The vehicle is still operational, I am however concerned that the problem may worsen.

When the car was still only a few months old, I began to experience brake shudder in the streering wheel when slowing down and stopping. Returned car to dealer for brake related complaint. They turned only front rotors. Refused to even look at rears. Returned again a few months later for same problem. Service manager said rotors were within factory specs and refused to do anything about it. Thrid time into dealer, rotors were turned again. This is the 4th time I have this problem. Car is beginning to shudder badly when braking. Calls to dealership owner unreturned. Call to Pontiac customer service led to absolutely no offer of help or resolution. My Pontiac case no. Is 99050789. There is already a tsb on brake problems on all 1998 F-bodies, that is camaro and Firebird models. GM should be forced to replace under warranty. It is not safe to turn the rotors anymore. I need some help here.

The front brake rotors on my '98 Pontiac Firebird started warping at 10,000 miles, they got to a point where I came close to losing control of the vehicle on rain slicked roads. The extreme pulsating of the brakes makes the car very hard to control on wet roads. The warping of the rotors gets worse as the brakes get hot. When starting out in the morning the warping isn't very noticable, but gets much worse as they heat up. Which makes it diffcult for the service dept. They check the brakes cold. After much complaining the dealer replaced the rotors at 13,417 miles. They started to warp again at about 16,000 miles. The dealer told me it was normal wear, and that it must be my breaking habits. Later the manager told me that break problems are a very common complaint with GM. I don't know what to do at this point and I hate to touch the brake pedal at highway speeds due to all of the shaking of the car. I really feel that this is a major saftey issue. The combination of the antilock brakes and the severe pulsating makes for a dangerous situation. Your help in this would be greatly appreciated.
