Disc brake with pad pressed only at ends where antinodes of vibration occur

摘要

A pad is engaged by a rotor by hydraulic pressure whereas another pad is engaged by the rotor on the other side thereof by a pair of pawls of the caliper under reaction. The reaction of the caliper is imparted to the other pad in a plane where a pair of the pawls of the caliper are opposed to the other pad and in a position at the marginal edges of the other pad, thereby minimizing squeal when the brake is applied.
