Service Brakes
WARNING: This page does not describe the selected car, but rather 32 other vehicles, including the 1992 Pontiac Sunbird, 1992 Pontiac Grand Prix, 1992 Pontiac Grand Am, 1992 Pontiac Firebird, and 1992 Pontiac Bonneville. However, it is still accessible from the selected car via links, so may be relevant.
Disc brakes are continually self-adjusting. Caliper piston seals are designed to retract pistons enough to allow brake lining to lightly brush rotor. Sliding caliper design compensates for lining wear.
