Friction and wear characteristics of two different automotive brake drum materials; conventional cast iron and AI-MMC, were experimentally studied. Friction stability and changes in temperature and torque during drags and stops test were measured by inertial brake dynamometer and wear test system. Brake dynamometer was used to obtain the amount of wear. And wear surfaces were observed by SEM and analyzed by XRD. Also the changes in friction coefficients, temperature and torque were measured by wear test setups under various load conditions. In this study, AI-MMC was shown to be more stable than cast iron in changes of temperature, friction coefficient and torque values; these experiments have been done under various sliding speed or load conditions.
