PISTON OF CALIPER BRAKE FOR VEHICLE

摘要

The present invention provides a piston of a caliper brake for a vehicle, allowing force of the piston pushing a brake pad to be uniformly applied to the brake pad, thereby minimizing one-sided wear of the surface of the brake pad, which is in contact with the disc. The piston of a caliper brake for a vehicle is a piston pushing the brake pad when brake oil is injected into a wheel cylinder and comprises a piston body and a pad contact part. The piston body is moveably included in the wheel cylinder and has one end and the other end sequentially positioned in a direction where the brake oil is injected. The pad contact part is included in the other end of the piston body and is in contact with the brake pad. The pad contact part has a contact surface having a rectangular shape and is in contact with the brake pad.
