Title:
DISC BRAKE DEVICE
Document Type and Number:
Japanese Patent JP2015175442
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a disc brake device capable of making removal performance for removing foreign substances of a disc rotor, and the reduction of a damage to the disc rotor, compatible.SOLUTION: A disc brake device is equipped with a disc rotor 3, and a brake pad 2. The brake pad has a friction member 21 for grinding a friction surface when frictionally contacting with a friction surface 31 of the disc rotor, ringing members 22 and 23 having high grindability for grinding the friction surface rather than the friction member, and thermal deformation members 24 and 25 whose shapes change with temperature change. By the deformation of the thermal deformation members with a temperature rise of the brake pad, the grinding members are shifted from a state incapable of contacting with the disc rotor to a state capable of contacting with the disc rotor.
