A spring member for disc-brake calipers is interposed between a lateral edge of at least one pad and reaction surfaces of the caliper so as to act resiliently on the pad. The spring member comprises a `U`-shaped portion suitable for forming a connection with a protuberance of the reaction surfaces, a first resilient portion suitable for acting on the pad in a tangential direction, and a second resilient portion suitable for acting on the pad in a radial direction. The first and second resilient portions constitute a single body projecting from a first connection end of the first resilient portion that is connected to the `U`-shaped portion, so that, when the at least one pad is in a mounted configuration, it is acted on resiliently by the spring member both in a radial direction and in a tangential direction.
