  • Spring for retracting and retaining a pad in a caliper type disc brake assembly
    Publication number: 20020189911
    Abstract: A disc brake uses retraction springs arranged in directions transverse to the direction of movement of the brake pads. The springs thus apply both tangential and radial forces to the brake pads to both retract the pads and to reduce rattle. In the preferred embodiment, the springs are S-shaped and attached to the pad backing plates by insertion of the ends of the springs into holes in the backing plates.

  • Automatic adjustment for disc brake pad
    Patent number: 6397983
    Abstract: A mechanism for a sliding-pin type disc brake assembly provides a gap between a brake pad and the rotor. The mechanism includes a bushing that receives a sliding pin and a resilient element between the end of the pin and the end of the bushing. The pin reciprocates in the bushing during operation of the brakes, and the bushing moves along the bore as the brake pads wear.
