Abstract: A braking unit has (1) at least two brake shoes, each with a friction lining; (2) at least one brake disk rotor each of the outer surfaces of the brake disc rotor at least partially forming a friction surface of a ceramic-metal composite material for each friction lining respectively; and (3) at least one brake application device that acts on the brake shoes during braking operation. The friction linings of the brake shoes cover at least 15% of the friction surface of the brake shift rotor. The at least one brake application device is arranged so that the pressure which acts on the brake shoes during the braking operation acts essentially evenly on the friction surface.

Abstract: A floating-caliper disc brake is designed to prevent both tangential and radial oblique wear of the brake linings, especially under high brake stress. To achieve this, the floating caliper, which is guided displaceably on a brake carrier in the direction of the disc axis and carries a brake piston and which engages over the brake disc, forms a frame which in the transitional region of the transverse frame leg on the run-out side, extending in the direction of the disc axis, and of the longitudinal frame leg supported on one brake pad is more pliant than in the transitional region between the longitudinal frame leg and the transverse frame leg located on the run-in side. The brake piston is arranged in the frame so as to be offset in the forward direction of rotation of the brake disc relative to the surface center of gravity of the brake pad actuable by the said brake piston, and the longitudinal frame leg supported on one brake pad extends level with the brake piston.
