In a disc brake having brake pads (22) accommodated inside openings (14) formed in a support member (12), the external edge (34) of the lining carrier plate (24) of each pad has at least one projecting part (54) accommodated inside an aperture (56) formed in a caliper (36) straddling the disc (10). A stud (58) made of a wear-resistant material projects from each part (54) toward the disc. Thus, in the event of the pad (22) slipping between the support member (12) and the disc (10) when the friction lining (26) is totally worn and the disc is worn, the projecting part (54) bears against the edge of the aperture (56), creating a torque which brings a stud (58) into contact with the peripheral edge (10c) of the disc. The pad is thus prevented from escaping, the driver of the vehicle is alerted by the noise resulting from contact between the stud (58) and the disc (10 ), the loss of efficiency of the brake is partially compensated, and the disc (20) is irreversibly damaged so that it is necessary to change it at the same time as the pads (22).
