Abstract
A disk brake has a brake piston for biasing pads against a disk. The piston is arranged so that the center of its biasing force is offset toward the leading disk side from the center of the frictional surface of the pad. Also, the piston is arranged so that the center of the biasing force is offset toward the center of the disk from a line extending in the tangential direction of the disk and passing the center of the frictional surface of the pad. In another arrangement, a disk brake has a plurality of brake pistons adapted to bias respective pads. One of the brake pistons is located at the leading disk side and has a greater pressure bearing area than that of the other brake piston at the trailing disk side. The brake pistons are arranged so that the center their biasing forces are offset toward the center of the disk from the line extending in the tangential direction of the disk and passing the center of the frictional surfaces of the pads.
