<p>PROBLEM TO BE SOLVED: To provide a disc brake device which can prevent eccentric wear of a brake pad and squeaking of brake in both cases of advancing and reversing the vehicle. SOLUTION: A long hole 50 is provided in the arm part 48 of callipers 30, which are supported by a torque member 90 movably along the long hole 50 toward the rotating direction of a disc rotor 18. When a piston and the claw 64 of callipers 30 put an inner pad 74 and outer pad 72 in pressure contact with the disc rotor 18 using a hydraulic force and its reaction force, the piston 36 and the friction members 84, 86, 88 furnished on the claw 64 are put in pressure contact with the disc rotor 18, and the friction members 84, 86, 88 have friction with the disc rotor 18 and are drawn to downstream in the rotor rotating direction at that time. Accordingly the callipers 30 move to downstream in the rotor rotating direction at that time, which will prevent squeaking in braking in both cases the vehicle is advancing and reversing.</p> |
