Abstract

In order to meet safety standards,  several systems have been studied and developed. The brake systems are one of the most critical systems in the vehicle, other than having an air bag, good suspension systems, good handling and stable cornering. Passengers may be placed in a dangerous position without a braking mechanism in a car. It is therefore important that all vehicles have a proper braking system. Braking is a mechanism that transforms the vehicle's kinetic energy into mechanical energy. The disc brake is a system which is used to de-accelerate or stop wheel rotation. The wheel is attached to a brake disc or rotor, typically made of cast iron or a ceramic composite. By acting mechanically, hydraulically, pneumatically or electromagnetically on both sides of the disc, the friction material of  the brake pad mounted on a system called a brake calliper is forced to stop the wheels. For the investigation of how disc brake functions more effectively, it is important to understand action force and friction force on the disc brake with new material, which can help minimise heat generation and provide better tribological performance.
