SUMMARY: CORROSION IN THE REAR BRAKE CALIPER PREVENTS AUTOMATIC ADJUSTMENT FOR PAD WEAR. THIS MAY EVENTUALLY CAUSE LOSS OF REAR SERVICE BRAKE AND PARKING BRAKE. GM HAS ADDED CORROSION PROTECTION AND CHANGED SPRING RATE TO CORRECT PROBLEM. SAME BASIC DESIGN USED ON ALL MODELS IDENTIFIED.
An investigation is not a finding of a defect, and closure does not prove a vehicle is problem-free.
