Abstract
A brake pad lining composition is provided that includes a friction modifier for adjusting a coefficient of friction of the brake pad lining and a strengthener for providing structural integrity. The composition also includes a fly ash filler for increasing the volume of the brake pad lining. A binder, such as phenolic resin, holds the friction modifier, the strengthener, and the filler together. By utilizing fly ash as a filler, the cost of the brake pad may be significantly reduced. Design of the brake pad lining may be simplified and the filler used more effectively by achieving a desired ratio of fly ash and binder, and then adding the friction modifier and strengthener to systematically adjust the brake lining properties.
