Abstract: A disk brake pad and backplate assembly comprises a metal backplate formed with a number of abutments projecting from one face thereof, and a disk brake pad of a fully cured friction material composition, one face of said disk brake pad being provided with recesses wherein said abutments are received, together with a layer of an elastomeric adhesive to bond said pad to said backplate.

Abstract: A brake lining is made from a preform which has been formed by a compression step parallel to that surface of the brake lining preform which is to be the braking surface of the lining in use and has subsequently been compressed in a direction substantially normal to said surface to form the lining. The preform can be made by dewatering an aqueous slurry of the brake lining ingredients prior to the first compression step.

Abstract: Non-asbestos brake pads made of reinforcing, temperature resistant, web-forming fibers such as aromatic polyamide pulp, optionally including other fibers and friction and wear modifiers is described. The brake pads have an actual density not greater than 88% and not less than a 60% theoretical density. The pads are made by the slurry process in which the pad-forming constituents are fed as a slurry into a mold, dewattered and compressed, dried to a preform then heated and pressed to consolidate the preform to substantially the finished density without completely curing the binder. The consolidated pad is then baked to fully cure the binder.
