With the increasing technological development in the area of motors, heavy–duty vehicles have been suffering an increase in size and in load capacity. Friction brakes are to decelerate a vehicle by transforming the kinetic energy of the Vehicle to heat, via friction, and dissipating vibration that heat to the surroundings, which produces excessive heat on lining surface. This shows increase in frictional area will definitely reduce the load on brakes by sharing the energy of the vehicle. So the above- factor is taken into account and finally reduction in inertia forces on rotating shaft by providing more frictional area is discussed on this paper. Also give details about applying the frictional force on differential gear shaft. To achieve this inner shoe, which is less than the size of the outer shoe, is provided as per the design of the system developed with the aid of solid works modeling tool. This can be actuated by a specially designed cam, which will actuate both outer shoe and inner shoe respectively. During braking the outer shoe will engage previously to absorb energy in the drum before the inner shoe get actuated. When the cam moves both the shoe remaining energy in both shoes share the vehicles. This entire system is analyzed by using FEA tool ANSYS 14.0 to determine the thermal stress developed in it. These results are compared with the conventional braking system.
