<p>PROBLEM TO BE SOLVED: To produce a high brake effect by a servo effect by generating self- boosting at a disc brake. SOLUTION: A device forms a power point constitution wherein the power point C of a caliper 4 is contained between a piston 1 and a friction material 5, a piston 2 and a friction material 6, a cylinder 3 or the caliper 4 and a friction material 7, and the power point A of the piston 1 and the power point B of the piston 2. The friction material 5 is forced contact-bonded at one surface of a disc rotor 8 in the power point A of the piston 1 and the friction material 6 is contact-bonded thereon in the power point B. Through a reaction force to extrusion by an oil pressure on the pistons 1 and 2, the cylinder 3 and the caliper 4 are slid and the friction material 7 is contact-bonded to the opposite surface of the disc rotor 8 in the power point C of the caliper 4. Operation of the power points A, B, and C generates a repulsion force by inertia and the centrifugal force of the disc rotor 8, the friction material 5, 6, and 7 are pushed back. The generation of selfboosting performs the stop of rotation movement of the disc rotor 8.</p> |
