Abstract
A brake backing plate has a friction surface for receiving a friction pad material. The brake backing plate has multiple protrusions are protruding out of the friction surface. One or more protrusions have an enlarged section for facilitating engagement between the friction surface and the friction pad material. In an embodiment, the enlarged section is formed by pressing the distal end of one or more protrusions.
Claims16
A brake backing plate comprising:
- a friction surface for receiving a friction pad material thereon;
- and
- multiple protrusions protruding out of the friction surface, one or more of which protrusions have an enlarged section for facilitating engagement between the friction surface and the friction pad material.
The brake backing plate as claimed in claim I wherein each protrusion has a proximal end where the protrusion is protruding out of the friction surface and a distal end opposing to the proximal end, and the enlarged section is formed at the distal end of one or more protrusions.
A brake backing plate treating apparatus comprising:
- a protrusion forming unit having multiple blades for forming multiple protrusions on a friction surface of a brake backing plate which receives a friction pad material thereon;
- and
- a deforming unit for deforming one or more protrusions formed by the protrusion forming unit to provide an enlarged section on one or more protrusions for facilitating engagement between the friction surface and the friction pad material.
A method for treating brake backing plates, the method comprising steps of:
- forming multiple protrusions on a friction surface of a brake backing plate which receives a friction pad material;
- and
- deforming one or more protrusions to provide an enlarged deformed section on the one or more protrusions for facilitating engagement between the friction surface and the friction pad material.
