Two problems related to brake disc have been reported for the 2003 Chevrolet Silverado. The most recently reported issues are listed below.
After hearing grinding noises, I inspected rear brakes and found rear inner brake pads had prematurely worn out. After disassembling rear brakes found pads frozen (stuck) on pad guides (had to force off with hammer) which prevented pads releasing from rotor and caused uneven and premature wear of pads and destroyed rotors. New pads were purchased and upon installation realized even new pads would not slide freely on pad guides. Local chevy dealer states they are unaware of any known problems. After searching numerous forums on internet and speaking with other Silverado owners found this is a common problem yet manufacturer does not want to take responsibility. To avoid this problem from recurring I had guide notches on pads machined slightly oversize than oem. So far no problems to report. If I can figure this out why cant gm.
The rear disc brakes wear out prematurely. They wear completely down to the rotors before one is aware that brakes are bad. Contacted the dealer. However, they will not do anything to assist the consumer.
