Bendix Single Piston Sliding Caliper

Fig. 1 Disc brake assembly:

The Bendix single piston sliding caliper disc brake is standard equipment on some truck applications, while on other trucks it is used only in Hydro-Boost power brake applications with both front disc brakes and 4 wheel disc brakes. On 4 wheel disc brakes, the front and rear systems are identical.

The sliding caliper attaches to and slides on the steering knuckle. The caliper assembly is held in place with a support key and spring Fig. 1. A screw prevents the key from sliding on the steering knuckle. The linings are riveted to the brake pads. The inboard and outboard brake pads are not interchangeable.
