In a disc brake caliper assembly (10) a pair of opposed brake pads (12,13) are carried by a single supporting pin (21) on opposite sides of a brake disc (11). The supporting pin (21) is, forwardly offset from a central radial plane through the brake pads (12,13) in the normal forward direction of brake disc rotation. A spring (26) for separating the brake pads (12,13) from the disc (11) on brake release and for reducing rattle of the brake pads (12,13) comprises a pair of resilient wing portions (28,29) extending laterally from a central spine portion (27), each resilient wing portion comprising a laterally extending portion (28a or 29a) leading to a downwardly and inwardly extending return portion (28c or 29c). The return portions pass obliquely over upper edges of the brake pads (12,13) to bias them axially apart and radially downwardly. The contact between the return portions (28c, 29c) and the brake pads (12,13) is in the radial centre plane of the brake pads to avoid twisting of the brake pads on the pin (21) in use. The pin (21) and spring (26) may be made in one piece. <IMAGE>
