Disk brake friction pad for vehicles

Caliper body of disk brake for vehicle

One embodiment of the present invention provides a caliper body including an acting portion having a cylinder bore; a union boss portion having a union hole; and a bleeder boss portion having a bleeder hole. The union boss portion is formed at a central portion of a side surface of the acting portion in a circumferential direction of a disc brake rotor, the side surface being opposite to a side surface facing the disc brake rotor. The bleeder boss portion extends from an outer circumferential side of the bottom wall of the cylinder bore to the union boss portion. The union boss portion and the bleeder boss portion form a continuous projecting portion such that the union boss portion projects further outwards than the bleeder boss portion.

Vehicle disc brake caliper body

One embodiment provides a vehicle disc brake, including a caliper body, a caliper bracket, a pair of friction pads and pad retainers. Lengths of a part of reacting claws of the caliper body are set so that distal end portions thereof are disposed further radially outwards in a radial direction of a disc brake rotor than inward pieces of retainer portions of pad retainers. And, distal end portions of the inward pieces are brought into abutment with lug pieces of the friction pads in a position which lies further inwards of the caliper body than circumferential end faces of these reacting claws.
