Abstract: A disc brake device in which uneven wear on the brake pads is prevented. Each brake pad has a set pin hole at one end in which a set pin is fitted, and a torque-receiving component for receiving braking torque in the other end. The pistons for pressing the brake pads are composed of first and second pistons. A center 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.

Abstract: A synchronizing brake device for a vehicle is provided with a first brake, a second brake, a synchronizing brake operating lever that synchronizes and operates the first and second brakes, an equalizer that distributes the control force of the synchronizing brake operating lever to the first brake and the second brake, a hydraulic master cylinder that generates hydraulic pressure for operating the first brake and first brake control force transmitting member which transmits control force from the equalizer to the hydraulic master cylinder and which is configured by a synchronizing member operated by the equalizer and a knocker that presses the hydraulic master cylinder by the operation of the synchronizing member. The knocker is provided with a knocker operating lever that can press the hydraulic master cylinder by being directly operated without depending upon the synchronizing member.
