In accordance with the invention, a hydraulic disk brake for bicycles is provided which includes a brake caliper 1, 101, a brake piston 8, 108, 208, and a guide cylinder 2, with the aid of which the brake system can be pre-adjusted in a coarse manner with respect to the bicycle frame. The total clearance (=2x"s"), of the brake linings 18a, 18b is capable of pre-adjustment. The central position of the brake caliber 1, with respect to the brake disk 21, can be adjusted via an adjusting screw 22. The brake is arranged for constant, equal clearance on both sides of the brake disk 21 in the unstressed condition of the brake, such clearance being ensured on the basis of the spring-action, pre-tensioning of the brake piston 8, 108, 208, with respect to the brake caliper 1, as well as of the spring-action pre-tensioning of the brake caliper 1, 101 with respect to the guide cylinder 2.
