VEHICLE DISC BRAKE DEVICE

摘要

A disc brake device in which uneven wear on the brake pads (86, 86) is prevented. Each brake pad has a set pin hole (103a) at one end in which a set pin (lϑ1) is fitted, and a torque-receiving component (104) for receiving braking torque in the other end. The pistons for pressing the brake pads are composed of first and second pistons (81, 82). The center (113) of the first piston near the set pin is located further inside from the middle of the sliding range of the brake pads, and the distance from the set pin is extended, the second piston has a center located toward the torque-receiving component, farther than the first piston from the set pin, and in the middle of the sliding range of the disc rotor.
