The invention is related to a spot-type disc brake with a stationary brake carrier (19) at which a floating caliper (1) is slidingly guided which straddles the edge of a brake disc (10), with two brake cylinders (11, 12) which are positioned on the internal axial side of the brake disc (10) aside each other and whose brake pistons (13, 14) act on the brake shoes (5, 7) which are arranged on the same axial side and in circumferential direction of the brake disc (10) at a distance from each other. According to the invention a third brake shoe (6) is fixed on the external axial side of the brake disc (10) to the floating caliper (1), which brake shoe is positioned staggered in such a manner that its friction area point of gravity (36) comes to be arranged substantially between the other two brake shoes (5, 7) in the circumferential direction of the brake disc (10). Braking noises and brake rubbing are eliminated by this arrangement. Further advantages of the inventive brake are constituted by its ease of serviceability in view of an ease of mounting of the brake shoes (5, 6, 7) and by its floating caliper (1) which allows to be manufactured with ease and at but low cost and with but little material, and which simultaneously with a low weight affords an elevated stiffness and a large brake disc diameter.
