Disc brake pad mounting and retention system and method

摘要

A system and method are provided for mounting, removing and retaining brake pads in disc brakes, such as air-operated disc brakes utilized on commercial vehicles, in a manner which does not require the use of separate brake pad retaining devices while providing positive retention of the brake pad. A preferred embodiment includes a brake caliper mount having brake pad abutment surfaces having radially-oriented and lateral grooves which permit a brake pad with corresponding projections on is lateral sides to be inserted through an opening of the brake caliper into the radially-oriented grooves until the backing plate projections are aligned with the lateral groove, and advancing the brake actuator behind the brake pad to place the brake pad in an operating position in which the actuator prevents the brake pad from realigning with the radially-oriented grooves until the actuator is retracted to permit brake pad extraction.

主权项

1. A brake pad retention system, comprising:
a brake pad receiving feature of a caliper mount arranged to receive a brake caliper, the brake pad receiving feature being located inside an axially outer periphery of brake pad abutment portions of the caliper mount and arranged to receive a brake pad in a radially-inward direction through an opening of the brake caliper mounted on the caliper mount of a disc brake; a lateral brake pad retaining feature arranged to permit a brake application device of the brake caliper to advance the brake pad toward a brake disk while retaining the brake pad against radially-outward motion of the brake pad.
