The contact owns a 1998 Chevrolet Corvette. The contact stated while driving approximately 60 mph attempting to engage the brakes, the brake pedal would pulsate. The vehicle was taken to an independent mechanic for diagnostic testing. The technician diagnosed that the front brakes and rotors needed to be replaced. The manufacturer was not notified of the failure. The vehicle was repaired. The approximate failure mileage was 150,000.

Purchased car new.at about 5000miles started to notice vibaration in steering wheel when brakes were applied. At about 10000miles vibration was severe under hard braking.dealer[jon hall Chevrolet] determined all 4 rotors were warped and resurfaced at no charge.at about 15000 miles started to notice vibration again.car now has 22000 miles is out of warrantee and vibration is again severe under hard braking. I would like a General Motors representative to look into this problem. Dealer informed me this was a common problem with 1998 models.I beleive this is a serious safety defect which could result in an accident during high speed [60-70mph] braking and a recall should be issued to replace what is an obvious design defect.

Filed a complaint with GMC that rotors keep warping but they claim there's nothing wrong with the rotors.

Started to experience a vibration in the front end upon application of brakes at approximately 5000 miles. This condition continued to occur. The front brake rotors were resurfaced at 8678 miles. This was a temporary solution. By 15000 miles the same condition returned, front end vibration causing the steering wheel to shake when applying the brakes. This was very noticable at freeway speeds. The dealer replaced the front rotors at 15613 miles. At around 20,000 miles this condition returned, front end vibration steering wheel shake when brakes applied. Once again the front rotors were resurfaced. They do not seem to grasp the fact that this is not correcting the problem. In addition to the front rotors there have been two occasions that upon hard (emergency) type braking the ABS system did not appear to function correct. On both occasions there was an excessive amount of brake release which nearly caused an collison.
