ABSTRACT:
The caliper support key (10) includes two generally U-shaped metallic key members (20, 40) which are shaped complementary to one another. Each member (20, 40) has a radially outer arm (22, 42) which includes a radially outer arm end (28, 48) that extends further than and outwardly at an angle away from an associated radially inner arm (24, 44). The radially outer arm end (28) of the outer key member (20) includes at least one aperture (31) which is in axial alignment with at least one opening (33) disposed within the associated radially outer arm end (48) of the inner key member (40). The aperture (31) and opening (33) are aligned eccentrically relative to one another in a circumferential direction relative to the brake. The caliper support key (10) retains the caliper (70) in operational radial alignment with the support member (60), and provides compression of a resilient member (50) disposed between the key members (20, 40) when braking torque causes a circumferential movement of the caliper (70) relative to the support member (60). A retainer member (65) extends through the eccentrically aligned aperture (31) and opening (33) to be received within a receptacle (63) in the support member (60), and thereby retain the caliper support key (10) on the support member (60).
