One problem related to brake grinding noise has been reported for the 1997 Chevrolet Suburban. The most recently reported issues are listed below.
Power steering keeps fluctuating between feeling tight and sloppy. At certain points the steering wheel seems to be pulled from my grasp, and oversteering occurs. Steering also sometimes makes a moaning noise. Also, brakes need to be replaced every 20,000 miles. Last time I had brakes replaced at dealer, I had to return 5 times to have them corrected. I was told shims broke off the front pads and were binding. All I know is that I could see the rotors glowing blue and the brakes smelled like they were burning, they were also making a horrible grinding noise when they were warm.
