Abstract

A brake caliper is provided for applying a braking force to a wheel, rotor, disc, or the like. The caliper includes a brake actuator, an actuator housing, a bearing for rotatably and slideably receiving the brake actuator in the actuator housing, and a ramp for displacing the brake actuator in an axial direction in relation to the actuator housing between an inactive position and a brake-actuating position in response to rotation of the brake actuator. At least one braking pad is actuable to apply a braking force in response to predetermined axial displacement of the brake actuator. The ramp includes at least one contoured camming surface inclined in a counterclockwise direction and at least one contoured camming surface inclined in a clockwise direction. Axial displacement of the brake actuator is accomplished by camming engagement between the brake actuator and one of the contoured camming surfaces formed in the ramp block. The brake actuator is rotatable by operation of a pull lever fixed to an outer end thereof. An adjustor is provided for moving the ramp block in the axial direction to move the brake-actuating position of the brake actuator correspondingly closer to the disc o…
