Patent ID: 8657081

Claim:
A disc brake comprising: pad plates each having frictional pads; a piston and a caliper housing to press the pad plates toward a disc; and a shim attached to one surface of each of the pad plates to be pressed by the piston or the caliper housing, the disc brake further comprising: a coupling hook protruding from the shim and having a coupling protrusion at an end thereof; and a coupling hole perforated in each of the pad plates to allow the coupling hook to be inserted and coupled into the coupling hole, wherein the coupling hole is perforated in a central portion of the pad plate through both surfaces of the pad plate, wherein the frictional pads of each of the pad plates include a first frictional pad and a second frictional pad separately coupled to the other surface of the pad plate at opposite sides of the coupling hole so as to be separated from each other, wherein the coupling hook is press-fit into the coupling hole to prevent separation of the shim from the pad plate, wherein the coupling hook and the coupling hole are elongated in a radial direction of the disc, and wherein the coupling hook is integrally formed with the shim.
