Abstract—Through this paper an initiative is taken to put focus on a special technique of retarder mechanism which is used in automobile industries. In this technique retarder device is used to augment or replace some of the functionsof primary friction-based braking systems, usually on heavy vehicles. Friction-based braking systems are susceptible to ‘brake fade’ when usedextensively for continuous periods, which can be dangerous if brakingperformance drops below what is required to stop the vehicle-forinstance if a truck or bus is descending a long decline. For this reason, such heavy vehicles are frequently fitted with a supplementary system that is not frictionbased.
