Abstract
A disc brake of the type comprising a caliper or frame member straddling a rotary disc and slidable on two circumferentially spaced surfaces of a fixed member by at least one key. The key is associated to one of the members and defines a guide surface which slidably cooperates with a corresponding surface defined on the other member. According to the invention, the guide surface comprises at least one assembly of relatively small surfaces separated by two series of parallel and equispaced grooves, and a smooth continuous surface forming a frame circumscribing the assembly of surfaces.
