A disc brake includes a torque plate (14) which supports a caliper (20) via at least one pin assembly (24). The pin assembly comprises a first part (48) and a second part (50).

A disc brake includes a torque plate (14) which supports a caliper (20) via at least one pin assembly (24). The pin assembly comprises a first part (48) and a second part (50). The second part defines a first friction surface (55) with the first part and a second friction surface (57) with the caliper. The first friction surface generates less friction than the second friction surface to assist a rotor 12 in “knocking-back”a pair of friction elements (42) and (44), thereby substantially eliminating drag between the rotor and the pair of friction elements.

In a disc brake, a torque plate disposed adjacent a rotor to be braked, a caliper cooperating with a pair of friction elements to urge the latter into engagement with the rotor during braking, the torque plate and caliper defining substantially matching slots, a pin assembly disposed within the matching slots, the pin assemby movably mounting the caliper relative to the torque plate, the pin assembly including a first part secured to the torque plate and a second part engageable with the caliper, the second part being movable with the caliper during braking through a predetermined clearance defined by the first part, the first part cooperating with the second part during braking to generate a first friction force opposing movement of the second part relative to the first part, and the second part cooperating with the caliper to generate a second friction force opposing movement of the caliper relative to the second part, the first friction force being less than the second friction force.
