Brake Caliper: Description and Operation

Exploded View Of Delco-Moraine 48H Series Rear Caliper
Rear disc brake calipers include an integral parking brake mechanism. When the parking brake is applied, the lever turns an actuator screw which
is threaded into a nut in the caliper piston. As the actuator screw turns, the piston is forced out, applying force on the rotor. The piston contains a
self adjusting mechanism to keep the parking brake in proper adjustment and to ensure proper clearance when the parking brake is released.
