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

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.

A disc brake, comprising a rotor having friction faces on opposite sides thereof, a caliper cooperating with a pair of friction elements to urge the elements into engagement with the friction faces of the rotor to retard rotation of said rotor, a non-rotating torque member carrying said caliper in a substantially fixed circumferential position relative to said torque member, said caliper and torque member having at least a pair of axially extending recesses in registry with one another and the recesses cooperating to define an axially extending aperture between said caliper and torque member, elongated pin members slidably received in said axially extending aperture for movably supporting said caliper relative to said torque member and for normally positioning said caliper in a predetermined circumferential position relative to said torque member, the pin members slidably engaging each other at a surface of each pin members and each pin member having a transverse dimension, and a dual purpose resilient spring engaging and maintaining each pin member within the axially extending aperture, said spring having enlarged end members disposed within the aperture and each presenting a flat surface engaging a respective pin member to bias the respective pin member inwardly of said axially extending aperture, the enlarged end members having a transverse measurement no greater than said transverse dimension, and said enlarged end members disposed within the aperture so as to maintain the cicumferentail position of the caliper relative to the torque member if said pin members fail to effect said circumferential position.
