Brake disc provides friction force with minimum weight loss on application of brake. The pad material only experiences more wear and friction. Disc and pad materials are selected to give a stable and high coefficient of friction (0.25-0.40). COF is directly proportional to braking force generated and inversely proportional to the stopping distance. The aim of the study is to identify a new material for replacement of pad material in practice. In this study, wear, hardness and friction properties of E glass fiber with epoxy resin and cashew friction dust composite are studied and compared with brake pad material in practice. The hardness was measured using shore hardness tester. The wear and friction was measured using the pin on disc wear testing machine. The pad material was made as pin with cast iron as the disc material for wear studies. The wear studies were conducted for various load conditions and sliding velocities.
