A Disc brake is sliding friction couple made of rotor (disc) connected to the wheel and a stator on which the friction material (say brake pad) is mounted. The friction causes wear of Brake pads. The brake pad is characterized by the frictional behaviour brake pads are always subjected to wear. The behaviour of brake pad material related to wear under the influence of parameters like velocity of sliding, sliding distance. Brake pads should ensure continuous coefficient of friction, safety and durability. The use of asbestos material is being avoided to manufacture the brake pads as it is harmful and toxic in nature. Further it leads to various health issues like asbestosis, mesothelioma and lung cancers. Hence, in this study, the tribological behaviour of Aluminium Based Silicon Carbide is been tested under the wear study. In this concept, an attempt is made to try out Aluminum Matrix material for brake pads. Composite are of polymer, ceramic and metal matrix type. The use of composites is motivated because of good friction co efficient and wear resistant properties. The aim of this project is to design a heat resistant material for optimum friction coefficient (?) and to design a perfect composite material which has low wear rate at different temperature, load and velocity conditions. The Specimen is prepared using two different compositions of fillers. . The Experimental investigation of sample specimen is done by Pin on Disc Apparatus for validation of wear rate and Friction Co - efficient.
