Claim 13

A sliding caliper disc brake according to claim 7 having a pair of said removable pin means and including resilient means between the sliding surfaces of one of said pair.

Claim 14

A sliding caliper disc brake according to claim 7 including means for holding one of said parts against rotation whilst the other of said parts is rotated during formation and release of the sliding connection between said members.

Claim 15

A sliding caliper disc brake according to claim 7 wherein said second part has a formation by which said second part may be rotated and said first part has a formation by which said first part may be held against rotation and wherein said formations are both on the same side of the disc.

Claim 16

A sliding caliper disc brake according to claim 7 wherein said complementary opening is closed at one end and wherein sealing means seal the other end.

Claim 17

A sliding caliper disc brake comprising a rotatable disc, a torque plate member for fixing to a vehicle frame or the like, a caliper member straddling a minor portion of the periphery of the disc for moving friction pad means disposed on opposite sides of the disc into braking engagement with the disc, portions of the torque plate member being arranged to receive directly drag forces experienced by each of the pad means, motor means in the caliper member for directly urging one pad means onto one side of the disc to cause the caliper member to slide relative to the torque plate member to apply by reaction the opposite pad means to the other side of the disc, and a sliding connection between the caliper member and the torque plate member comprising a first component slidably received in an opening in one of the members, and a second component passing through an opening in the other of said members and being laterally adjustable therein into alignment with said first component, said first and second components having complementary screw-threaded portions by which said first and second components are locked together to clamp said first component to said other of said members.

Claim 18

A sliding caliper disc brake comprising a rotatable disc, a torque plate member for fixing to a vehicle frame or the like, a caliper member straddling a minor portion of the periphery of the disc for moving friction pad means disposed on opposite sides of the disc into braking engagement with the disc, portions of the torque plate member being arranged to receive directly drag forces experienced by each of the pad means, motor means in the caliper member for directly urging one pad means onto one side of the disc to cause the caliper member to slide relative to the torque plate member to apply by reaction the opposite pad means to the other side of the disc, and a sliding connection between the caliper member and the torque plate member comprising a first component slidably received in an opening in one of the members, and a second component passing through an opening in the other of said members and being laterally adjustable therein into alignment with said first component, said first and second components having complementary screw-threaded portions by which said first and second components are locked together to clamp said first component to said other of said members.
