Abstract: Brake disk wear pad plates have various different types of snap fasteners so that adjacent wear pads may be releasably joined together. Desirably, the brake pad plates are located on opposite sides of a brake disk core and thus are held together by the fasteners usually extending through the core. Generally, the snap fasteners may be of a projection-recess-type fitting in which the projection and recess matingly and releasably engage each other or of a common-component type wherein a structural part matingly and releasably engages both adjacent fasteners. When the brake disk wear pads are worn, the brake disk pad plates are readily disengaged from each other, new wear pads inserted into the brake disk plates and the wear pad plates once again snap fastened to each other.
