NOTE: One of the biggest advantages of a disc brake system is the foolproof self-adjuster. Not so with this rear GM system. The rear caliper adjusts off the parking brake. The parking brake is incorporated into the caliper. You must set the parking brake every time you park the car. The rear caliper piston utilizes a one-way clutch inside the caliper piston. When the parking brake is applied the clutch senses when there is 0.030 in. or more clearance between the friction material and the rotor on the inboard side. When there is more than 0.030 in. the clutch turns inside the piston adjusting it out keeping the rear brakes adjusted. If you do not set your parking brake every time you will start to lose brake pedal pressure (low and spongy) and the adjuster mechanism will not work any longer.
