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.
