Brake Caliper: Description and Operation
Fig. 1 Kelsey-Hayes Dual Pin Floating Caliper Disc Brake Assembly
The single piston, floating caliper disc brake assembly, consists of the rotor, caliper, pads and the driving hub. The caliper is mounted through bushings
and sleeves by two through bolts threaded into an adapter. Two machined abutments on the adapter position and align the caliper fore and aft. The
mounting bolts and bushings control the movement of the caliper and the piston seal to assist in maintaining proper pad clearance.
This assembly has an anti-rattle clip attached to the outer pad and an inner pad-piston retainer clip.
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.
A square cut rubber piston seal is located in a machined groove in the caliper bore and provides a seal between piston and caliper bore.
A molded rubber dust boot installed in a groove in the cylinder bore and piston keeps contamination from the caliper bore and piston. The boot mounts
in the caliper bore and in a groove in the piston.
