<p>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.</p> |
