Abstract

The invention relates to a disc brake brake pad, which is used for rubbing a disc to generate braking force. The brake pad comprises a bottom plate, at least one friction plate and a non-slip copper block. Two opposite sides of the bottom plate are respectively a front and a back, and the front is used to face the disc. Both the friction plate and the anti-slip copper block are arranged on the front side of the bottom plate and are used to rub the disc. Among them, the hardness of the anti-slip copper block is higher than that of the friction plate, so it is not easy to wear. In this way, when the friction plate is worn out, the non-slip copper block that has not been worn can continue to rub the disc to maintain a certain braking force, thereby prolonging the service life of the brake plate.
