The invention relates to a spring (40) for a disc brake of the type comprising a caliper (10) mounted slidingly parallel to the axis of a rotating disc (30) on a fixed support by way of at least two axial sliding surfaces (14, 18) formed on the caliper (10) and on the fixed support and maintained elastically in contact, and two friction members (22, 24) received in anchorage and in axial sliding motion in an opening (34) in the fixed support to become frictionally engaged with the opposed faces of the disc on actuation of a brake motor (32). The spring is disposed between the caliper (10) and the supporting plates (26, 28) of the friction members (22, 24) and exerts on the latter a radial force (R) directed approximately along a radius of the disc (30) and in the direction of the axis of the latter and a tangential force (T) perpendicular to said radial force (R) to urge each of the friction members (22, 24) tangentially to the circumference of the disc to ensure maintaining of the latter in a preferential lateral position, the spring elastically urging the caliper (10) radially toward the exterior to ensure maintaining in contact of the sliding surfaces (16, 18). The spring consists of a bent metal leaf comprising two main arms (42, 44) connected by a central bend (52) and a hooking arm (80).
