Brake Caliper: Description and Operation
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 friction material is bonded with rivets. The inboard and outboard brake pads are not
interchangeable.
