Abstract


Braking system in an automobile plays an important role to control the vehicle. Now a day’s, high speed vehicles with advanced technologies are launching in to the market by varying different design procedures. Therefore, an effective braking system is always required for a vehicle to have proper safety and comfort to the user in different environmental climatic conditions. Effectiveness of the braking system has to be considered, in addition to aesthetic consideration of an automobile in order to avoid accidents. After, the gradual phasing out of asbestos as a friction material, due its wide spread complaints as a carcinogenic material by world health organisation, people and industries are looking for suitable alternatives to replace asbestos friction material. In this work, an attempt is made to check the performance of the brake by altering the materials of the disc and pad of the braking system, which are supposed to be major components of the brake. The behaviour of the disc brake pad assembly is studied under high speed dynamic loading conditions. The results are compared with the experimental results available in literature, and the best combination of materials for disc and pad is suggested for the design related to high speed dynamic conditions of the automobile
