ABSTRACT:
A floating-caliper disc brake (10) includes a non-rotating torque member (36) which carries the caliper (22) in fixed radial position relative to the disc (12) via a pair of resilient assemblies (50). The torque member and caliper each have matching grooves (44, 46) which, when placed in registry, define a pair of apertures (48) between the caliper and the arms (38, 40) of the torque member. The resilient assemblies are received in the apertures (48) so as to yieldably space apart the caliper and the torque member. Brake torque is transferred from the caliper to the torque member by abutment surfaces defined on the caliper and on the torque member. The resilient assemblies provide for ready axial movement of the caliper relative to the torque member in the brake release condition by providing a light spring force which centers the caliper between the arms of the torque member. A much larger spring force is provided by the resilient assemblies if the caliper moves to either side of the caliper-centered position so that the caliper does not rattle against the torque member arms incident to vibrations and road shocks caused by vehicle operation.
