A sliding caliper disk brake is provided, in which a stationary brake carrier configured to carry a brake caliper includes two pairs of carrier horns, one pair of which supports a reaction-side brake pad and one pair of which supports an application side brake pad. The spacing between the reaction-side pair of carrier horns is larger than the spacing between the application-side pair of carrier horns. The reaction-side brake pad and reaction-side pair of carrier horns may be shorter than the corresponding application-side brake pad and carrier horns. The arrangement of the brake carrier, the brake caliper and the brake pads permits reduction in disk brake weight, cost and brake carrier stresses while providing desired brake thermal, mechanical and service life performance.
