One problem related to brake foundation components has been reported for the 2001 Chevrolet Blazer. The most recently reported issues are listed below.
Our 2001 chevy Blazer required brake service with 44000 miles. We selected tuffy auto service centers (warren, mi), our estimated cost was $180. During the brake service the tuffy service manager informed us that our rear brakes would require replacement, our cost for the rear was an additional $280. The service manager indicated that the rear brake disc-rotors were heavily corroded, service (rotor turning) was not an option and replacement required. Rear brake service at 44000 miles is highly unexpected, full replacement due to corrosion is unacceptable. Our assessment is that the disc-rotor material was not correctly specified (and/or perhaps a galvanic corrosion with aluminum wheels/iron hubs), the resulting excessive corrosion unexpected and a serious safety concern.
