METHOD OF SECURING A SHIM TO A BACKING PLATE AND SUBASSEMBLYFORMED THEREBY

摘要

A method of securing a shim against a first side surface of a backing plate, wherein the shim and the backing plate together comprise a subassembly for use in a brake assembly, the method comprises the steps of: stamping the first side surface of the backing plate so as to form a first extending pin and at least a second extending pi n spaced apart from the first extending pin, each of the pins being integrally connected to the backing plate, and stamping the shim so as to form a first aperture and at least a second aperture spaced apart from the first aperture whereby a respective edge circumscribes each aperture, wherein the position of the at least two extending pins is based at least in part on the position of the first and second apertures or the position of the first and second apertures is based at least in part on the position of the at least two extending pins; coupling the shim against the first side surface of the backing plate and aligning the first aperture with the first pin and aligning the second aperture with the second pin such that the pins extend through the apertures; deforming each respective pin sufficiently to directl y contact and lock down at least a portion of the edge of each respective apertures to secure the shim against the first side surface of the backing plate and wherein the respecti ve pins do not extend above the top surface of the shim after deformation; whereby the shun is resisted from shifting on the backing plate and the pins cannot interfere with a pist on or caliper that is in contact with the shim. A subassembly formed from the foregoing method is also disclosed.
