PURPOSE:To miniaturize a disc brake in its entirety, by constituting a disc rotor with two rotors, and by disposing pads among a guide device and both rotors. CONSTITUTION:A disc rotor 18 has a first rotor 19, a second rotor 21 and pads 27-33, and is guided by a guide block, slidably along the axle. Accordingly, a piston 10 is made in press-contact with the second rotor 21 through a pad plate 33 and therefore, a caliper 2 is guided by a caliper guide device under reaction force to move in the axial direction so that a lining 28 is made in press-contact with the first rotor 19 through a pad plate 27. Therefore, four press-contact point are obtained between the disc rotor 18 and the pad, and therefore, a large brake torque may be obtained even if the diameter of the disc rotors 19, 21 are small, thereby it is possible to miniaturize the brake disc in its entirety. |
