  • Publication number: 20230140297
    Abstract: Provided is a method for manufacturing a brake pad used in a brake of a vehicle, which is capable of improving a limitation of separation of a friction material and a back plate of the brake pad. The method for manufacturing the brake pad includes manufacturing an intermediate plate and integrally pressing and molding a back plate and a friction material on both surfaces with the intermediate plate manufactured in a mold therebetween so that the back plate and the friction material are integrally coupled to each other by using the intermediate plate as a medium to manufacture the brake pad.

  • Publication number: 20230016971
    Abstract: Provided is a caliper unit for a brake of a vehicle, in particular, a compact caliper unit capable of reducing a size, a weight, and a production cost of a component and improving fuel efficiency. The caliper unit for the brake includes an inner pad and an outer pad, which press both surfaces of a disc to generate braking force, a torque member fixed to a vehicle body and coupled to be movable forward and backward so that the inner pad and the outer pad press the disc, or the pressing of the inner pad and the outer pad to the disc is released, a caliper housing including a cylinder to which a brake hydraulic pressure is applied and a reaction force support part configured to press the outer pad to the disc, and a piston installed in the cylinder and moving forward and backward depending on a state of the brake hydraulic pressure applied to the cylinder to press the inner pad to the disc.
