One problem related to brake disc has been reported for the 1998 Chevrolet Suburban. The most recently reported issues are listed below.
I have had to replace the disc pad 4 times in under 10,000 miles, I have had to replace the rotors twice in the same amount of time. I am now facing another rotor and brake pad replacement. The rotors warp very quickly and the pads do not last, seems to always have some pull when brakes applied in normal braking situations. Also, the vehicle pulls hard and wildly in emergency braking situations.
