Abstract

The invention provides a disc brake backing plate with an integrally formed spring hole plug. A blind hole is defined within the plate, terminating at a closed boss (plug) on the friction material- receiving surface of the plate. The blind hole is adapted to receive and secure an end of a conventional shoe retaining spring for mounting the finished brake pad within a disc brake caliper. The integral boss prevents friction material from entering the hole at the friction molding stage, relieving the manufacturer of the need to add separate blocking hardware. A method of manufacturing the plate with an integrally formed spring hold plug is also provided.

Claims (11)

1. A friction material plate for connection to a brake assembly fastener, comprising:
a) a contact surface for attaching the friction material to the plate; and b) a second surface opposing the contact surface, the plate defining a blind hole, a closed end of the blind hole impermeable to the friction material and proximate to the contact surface; and c) a gripper received within the blind hole for attaching the brake assembly fastener to the friction material plate.
2. The plate according to claim 1, wherein the closed end comprises a boss on the contact surface.
3. The plate according to claim 2, wherein the boss is integrally formed from the plate.
4. The plate according to claim 1, wherein the gripper comprises a burr.
5. The plate according to claim 4, wherein the burr is integrally formed from the plate.
6. The plate according to claim 4, wherein the burr is recessed within the blind hole between the second surface and the contact surface.
7. The plate according to claim 1, wherein the blind hole receives the brake assembly fastener.
8 8. The plate according to claim 4, wherein the burr receives and secures a portion of the brake assembly fastener.
9. A method of manufacturing a friction material plate for connection to a brake assembly fastener, the plate including a contact surface and a second surface, the method comprising:
a) forming a first hole through the friction material plate between the second surface and the contact surface; and b) applying force to the second surface proximate to the periphery of the first hole to form a second concentric hole beginning at the second surface and terminating before the contact surface, so that material is removed from the second surface and extends from the first hole at the contact surface to form a closed end which is impermeable to the friction material and proximate to the contact surface.
10. The method according to claim 9, wherein step (b) further comprises creating a boss at the contact surface.
11. The method according to claim 9, wherein the method further comprises:
c) applying force to the second surface to push material from a wall of the second hole into a protrusion on the wall of the second hole recessed between the second surface and the contact surface, the protrusion comprising a gripper for receiving the brake assembly fastener.
