One problem related to brake disc has been reported for the 1998 Chevrolet Corvette. The most recently reported issues are listed below.
In each failure of the rotor assembly, the vehicle began to vibrate terribly upon trying to stop and this usually is noticable at 15 mph. The dealership is terrific in attempting to repair the problem and the service manager at sewell is the best ever. . . Very attentive and concerned with this continous failure. I do not drive fast and as you can see, the vehicle is seldom driven accumulating only approximately 21,000 miles in 3 years but the rotor assembly fails at almost 7,000 miles each time starting with originaly equipment and the replacement parts also fail each time the problem is attempted to resolution. Steering is difficult when failure occurs and the vehicle vibrates.
