Ventilated disc for a disc brake consisting of a friction track (1, 2) and a disc hub (3) connected by means of pins (10) that are partly embedded as inserts anchored irremovably in the material of the track (1, 2) and partly inserted, in such a way that they can freely slide axially, in the material of the disc hub (3), the said friction track and disc hub being obtained in a single casting process by using a common core with the pins held in the core.
