Improved disc brake, of the type comprising a disc in the shape of a flat circular crown having at a point of its periphery, two facing braking pads fitted to press the disc inserted between said pads. The brake is characterized in that at the disc inside perimeter there is a plurality of radially-arranged entrants, regularly distributed and preferably back-bent with respect to the rotation sense of the disc. Each of the brake pads facing the disc having on the face rubbing said disc, an arcuated recess in the sense associated with the previously cited entrant, from a mutual interference area to the pad external profile, an air communication is formed at the mutual interference area of the entrant and the recess which is cooling the brake unit.

[ What is claimed is:] [1.]1. IMPROVED DISC BRAKE of the type comprising a disc (1) in the shape of a flat circular crown having a periphery circular sector between the two brake pads (4), said pads (4) facing each other and being fitted to be pressed against the disc (1), characterized in that the disc (1) has a plurality of entrants (3) at the inside profile in a manner of turbine blades; in that each of the pads (4) has an arcuated recess (2) at the rubbing face with the disc (1), the recess starting near the pad (4) external edge with respect to the disc (1) operating position and leads down to the inside portion also with respect to said operating position, said recess (2) being deemed as an extension of the entrants (3) of the disc (1) when located facing one of them; in that said pad (4) is fitted to match a mutual interference area with each entrant (3) of the disc (1) when the disc (1) rotates; in that the recess (2) on the pad (4) has a blind end matching with the entrant (3) blind end at an interference area, in such a way that an air communication is formed between said entrant (3) and the recess (2) in the passage of said entrant (3) between the pads (4); and in that the entrants (3) are radially-arranged and back-bent with respect to the rotation sense and being fitted to start an air centrifugal stream.
