A disk brake mounting member having a pair of left and right arms spaced apart from each other in the circumferential direction of a disk. A pair of left and right pin holes are formed in the left and right arms, respectively, with different bore diameters. The pin holes are fitted with sliding pins, respectively, which support a caliper slidably in the axial direction of the disk. The arms are previously provided with left and right projections near the respective open ends of the pin holes so as to be in symmetry with each other. At least one of the projections is formed into a shape different from that of the other when the pin holes are formed in the arms by machining. Also disclosed is a method of producing the disk brake mounting member. According to this method, a mounting member is first cast to have left and right projections. One of the projections is then cut off.

Mounting member for disk brake and method of producing the same

A disc brake mounting member has a pair of mounts to be secured to a non-rotating part of a vehicle on one side of a disc rotatably provided in the vehicle. The mounting member also has a pair of arms positioned on the outer side of the mounts in a radial direction of the disc for supporting a caliper so that the caliper can slide in the direction of the axis of the disc. The mounts are integrally formed with abutting surfaces, installation holes, and projections. Projections function as stoppers to be engaged by the non-rotating part of the vehicle when the mounting member is inserted between the disc and the non-rotating part.
