Abstract: The present specification discloses a clamp member and a torque taking member with the clamp member being slidably mounted on the torque taking member by at least one sliding pin connection, whereby the clamp member can slide relative to the torque taking member to apply a friction pad to each side of a braking disc. The at least one pin connection comprises a pin which engages in a bore with a flexible sleeve located on the pin, the flexible sleeve engaging the wall of the bore. The pin has a two part construction with the flexible sleeve located between said parts, said parts being secured together so as to deform the flexible sleeve radially outwardly into engagement with the wall of the bore.
