  • Disc brake and positioning device therefor
    Patent number: 4460068
    Abstract: A disc brake includes a positioning device (40) which is pressure responsive to control the amount of retraction for a piston (22) within the disc brake. The positioning device includes a plug (44) movably and sealingly carried within the piston (22) and a pair of legs (48, 50). The plug (44) cooperates with the pair of legs (48, 50) to move the latter to a position in spaced relation to a caliper housing (12) when the pressure level within a pressure chamber (28) is above a predetermined value. A spring (52) cooperates with the plug (44) and the pair of legs (48, 50) to engage the latter with the caliper housing (12) when the fluid pressure within the pressure chamber (28) is below the predetermined value.

  • Disc brake and anti-rattle spring therefor
    Patent number: 4410068
    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.
