Brake drum is one of the important components of braking system in automotive applications. Brakes of an automobile generally fail when the working stress exceeds the maximum permissible stress and excessive heating of brake drum. Heat remained in drum without being released is key parameter for failure of brake drum. Weight of brake drum is another key parameter which is to be considered. In this paper, these two parameters are satisfied by modifying the brake drum into rectangular and

The rate of heat transfer and fin effectiveness are calculated theoretically. The model is then designed in CATIA V5R17 software and the heat flow and temperature gradient along the surface are analyzed using two different materials for brake drum i.e. grey cast iron and aluminum 6061,temper t6 by using ANSYS R16.0 software and the results are compared.
