Shim attachment

A method of maintaining a shim against a first side surface of a backing plate with at least one staple, wherein the shim and the backing plate together comprise a braking subassembly for use in a brake assembly, wherein the staple comprises a head section;

• a body section coupled to the head section, the body section having a concavity so as to form a recessed region therein and permit a portion of displaced backing plate material to flow therein;
• and a leg member, shaped for permitting a portion of the material comprising the backing plate to be displaced towards and into the recessed region as the leg member is piercing the first side surface of, and progressing into, the backing plate, wherein the method comprises the steps of:
• piercing the backing plate by driving the leg member into the first side surface of the backing plate;
• causing a portion of the material comprising the backing plate to flow in a direction towards and into the recessed region;
• and
• causing the body section to be driven into the backing plate so that displaced material fills the recessed region of the body section;
• whereby the staple is resisted from being removed from the backing plate, and the shim mounted onto the first side of the backing plate is maintained thereagainst at least in part by contact of the head section against the shim.

A subassembly for use in a brake assembly, the subassembly comprising:

• a noise dampening device having an adhesive side and a second side;
• a steel backing plate having a first side on which a braking pad is mounted and a second side for receiving the noise dampening device;
• and
• a staple, for assisting in the coupling of the noise dampening device to the second side of the backing plate, the staple comprising a head section;
• a body section coupled to the head section, the body section having a concavity so as to form a recessed region therein;
• and a leg member, shaped for permitting a portion of the material comprising the backing plate to be displaced towards and into the recessed region as the leg member is piercing the first side surface of, and progressing into, the backing plate;
• wherein upon insertion of the body section into the backing plate, the concavity of the body section causes the displaced material to fill the recessed region;
• whereby a noise dampening device mounted onto the second side of the backing plate and secured thereto at least in part by the head section is inhibited from movement on and separation from the backing plate.
