A sliding caliper disc brake comprises a torque member, a caliper member slidably mounted on the torque member for straddling a minor portion of the periphery of a rotatable disc, and an actuator for directly urging a friction pad against one side of the disc to cause the caliper member to slide relative to the torque member to apply by reaction an opposite friction pad onto the other side of the disc. The caliper member is slidably mounted on the torque member by a sliding connection which includes a pin element having a portion slidably received in one of the members. The latter pin element is connected to the other of the members by an arrangement which permits lateral displacement of the pin element with respect to the other of the members. Laterally extending friction surfaces are provided on the pin element and on the other of the members. The latter friction surfaces are axially biassed towards each other so as to provide frictional resistance to the aforegoing lateral displacement. |
