A floating-caliper disc brake (10) includes a non-rotating torque member (36). A caliper (22) straddles the brake disc (12) and is carried in fixed radial and circumferential position by the torque member (36). Axial movement of the caliper (22) relative to the brake disc (22) is provided for by roller members (58) between the caliper (22) and the torque member (36). The torque member (36) and the caliper (22) both have axially-extending grooves (52, 54) which in registry cooperate to define axially-extending apertures (56) between the caliper and the torque member. The roller members (58) are received in the axially-extending apertures (56) between the caliper (22) and the torque member (36). The roller members (58) are the sole torque-transmitting structure between the caliper (22) and the torque member (36). Rolling of the caliper (22) on the roller members (58) provides for axial movement of the caliper (22) relative to the brake disc (12) and the torque member (36).
