Brake Caliper: Description and Operation
Kelsey-Hayes Single Piston Sliding Caliper

Fig. 2 Piston Seal Function
The caliper assembly consists of a rotor, caliper, shoes and linings, and adapter. The single piston caliper assembly floats through a rubber bushing on a
single pin, threaded into the adapter. The bushing is inserted into the inboard portion of the caliper. Two machined abutments on the adapter, position
and align the caliper fore and aft. The guide pin and bushing controls the movement of the caliper and the piston seal, to assist in maintaining proper
shoe clearance.
This assembly has three anti-rattle clips. One is on top of the inboard shoe, one clip is on the bottom of the outboard shoe, and one clip is on top of the
caliper.
All of the braking force is taken directly by the adapter. The caliper is a one piece casting with the inboard side containing a single piston cylinder bore.
