Disc Brake System: Description and Operation

The caliper assembly consists of a pin slider caliper housing, inner and outer pad and lining assemblies and a single piston. The caliper slides on two pins which also act as attaching bolts between the caliper and caliper bracket. The inner and outer pad and lining assemblies are attached to the caliper bracket by pad retainers. A wear indicator is attached to the inner pad and emits a noise when the lining is worn to a point when replacement is necessary.
