  • Spring for a disc brake
    Patent number: 4560037
    Abstract: A spring for a disc brake wherein a caliper cooperates with a pair of friction elements to engage the latter with a rotor during braking. A torque member carries the caliper relative to the rotor and opposes movement of the pair of friction elements with the rotor. The spring extends from the caliper to one of the pair of friction elements to releasably attach the latter to the caliper and also bias the one friction element into a substantially anti-rattle abutment with the torque member whereby rattling noises for the one friction element are reduced or eliminated.

  • Wire spring for a disc brake
    Patent number: 4487296
    Abstract: A wire spring (60) for a disc brake includes a coiled portion (62) with a pair of arms (64, 66) cooperating with the caliper via slots (70, 76) and with a friction element (24) via ends thereof (32, 34) in order to reduce rattle caused by the friction element while at the same time releasably attaching the friction element to the caliper assembly.

  • Disc brake assembly
    Patent number: 4448289
    Abstract: A disc brake assembly includes a caliper assembly and a torque member with matching recesses for receiving a pin assembly and the pin assembly includes as an assembled part thereof, a wire element carried by a resilient member to permit installation of the pin assembly into the recesses and yieldably prevent withdrawal thereof.

  • Disc brake and antirattle spring therefor
    Patent number: 4415068
    Abstract: A disc brake (10) includes a support member (22) movably interlocking with a pair of friction elements (42, 44) to dispose the friction elements adjacent a rotatable brake disc (12). The friction elements define abutment surfaces (88, 90) movably engaging a caliper (60) straddling the brake disc (12) and friction elements (42, 44) so that the friction elements support the caliper. An axially-extending pin (110) is carried by the support member (22) and received in an axially-extending bore (112) defined by the caliper so that the caliper (60) is also supported by the axially-extending pin. The caliper (60) includes pairs of axially-spaced projections (96, 98, and 100, 102) and the friction elements (42, 44) define slots (92, 94) aligning with the projections. A pair of resilient members (104, 106) extend axially through the slots (92, 94) of the friction members (42, 44) and engage the projections (96, 98, and 100, 102) of the caliper to interlock the caliper (60) and friction elements (42, 44).

  • Disc brake assembly and resilient member therefor
    Patent number: 4330049
    Abstract: A disc brake assembly includes a caliper assembly which is operable to bias a pair of friction elements into engagement with a rotor. At least one resilient member cooperates with the caliper assembly and the pair of friction elements to releasably couple the latter to the caliper assembly. In addition, the one resilient member cooperates with the caliper assembly and one of the pair of friction elements to define an interlocking fit preventing movement of the caliper assembly in a radial direction relative to the rotor.
