PURPOSE: A support device of braking force of a disc brake is provided to ensure a braking operation, by continuously operating a damaged piston through the motion of a normal piston when one out of brake pipe lines is damaged. CONSTITUTION: Pads(12) are confronted each other. Pistons(14) are mounted to compress the pads. Pressure chambers are formed to give hydraulic pressure to the pistons. Brake pipe lines(18) are branched and connected from a master cylinder to the pressure chamber and supply a braking fluid for the pressure chambers. A linked member(20) connects both pistons and moves the pistons into a disc rotor(10). Wherein, The end parts of rods of the linked member are fixed to the center part of the pistons, the one out of the rods serve as a lever, centering a fixed hinge(24).
