摘要:
A disc brake assembly (10) includes a caliper (22) movably supported by a torque member (36). The caliper (22) and torque member (36) each have lateral recesses (44. 46, 48. 50) defining axially extending apertures (52, 54) between the caliper (22) and torque member (36), with a pair of wedge-shaped members (66, 68) disposed in each aperture to maintain the caliper in radial and circumferential position relative to the torque member while allowing lateral movement therebetween. The wedge-shaped members (66, 68) are biased inwardly by an improved dual purpose spring member (72) which traverses a portion of the exterior perimeter of the torque member (36) and engages the ends of the respective pins. The spring member (72) includes enlarged end members (74) each comprising a coil presenting a flat surface (75) for engaging the end of the respective pin (66, 68) to urge the pin inwardly of the aperture (52, 54), the enlarged end members (74) being disposed within the openings (90) of the apertures so that the enlarged end members (74) maintain the radial and circumferential position of the caliper (22) relative to the torque member (36) if the wedge-shaped pins (66, 68) are damaged or should fail.

摘要:
An adjustment assembly for a disc brake includes a nut (26) and a threaded stem (28). The threaded stem (281 defines a first diameter portion (72) and a second diameter portion (76) which cooperate to form a differential area sealingly engaging an inwardly extending partition. The partition also forms a passage (88) to cbmmunicate fluid pressure to both portions (72, 76) so that the differential area and pressure communicating passage are compactly arranged at the partition.
摘要:
A disc brake includes a caliper assembly (12) cooperating with a pair of friction elements (14, 16) to brake a rotor (10). A pin assembly (30) supports the caliper assembly (12) and includes a bolt (34) defining an axial spacing for a sleeve (36) which engages the caliper assembly (12) via a resilient bushing (32). The sleeve is permitted to move axially through a clearance (62) with each brake application and a spring (38) biases the sleeve and caliper to always retract through the clearance upon termination of braking.
