Brake Systems - DELCO-Moraine Single Piston Disc: Description

Single piston caliper is constructed from single casting, which contains one large piston bore in inboard section. Piston is formed from nickle-chrome plated steel.

NOTE: Use of abrasives, or re-mechining piston, will destroy plating.

There is no piston spring in bottom of caliper bore. Caliper is mounted on support bracket attached to suspension.

NOTE: On some models caliper is connected directly to steering knuckle.

Shoe and lining assemblies are constructed of stamped metal shoe with riveted lining. Outboard shoe and lining are thinner than inboard assembly and have ears at top and tab at bottom, bent at right angle to shoe. A cast iron rotor is used in conjunction with these disc brakes. It contains two machined braking surfaces, separated by ventilation fins. A groove is added to center of rotor braking surface to aid in reduction of brake noise.
