摘要：Brakes are one of the most important control components of the vehicle. They contribute very much in themovement of the vehicle. . Brakes are generally applied to rotating axles or wheels. The momentum or kinetic energy tostop the vehicle when in motion is converted to heat energy by the friction of brake pads and the rotors which is dissipatedinto the surrounding air. The main functions of brakes are mainly to stop the vehicle in shortest possible time and to helpin controlling the speed of the vehicle. However, with long term use of brakes many problems occur which results in brakefailure, leading to a fatal injury caused to the driver and co-passengers. One of the most important causes of brake failureare brake fades. Vehicle braking system fade, or brake fade, is the reduction in stopping power that can occur afterrepeated or sustained application of the brakes, especially in high load or high speed conditions. For elimination of brakefade, it is necessary for maximum temperature to be less than fade stop temperature. So, to have lesser temperature wealter the parameters dependent on it. Since, stopping time, density of material, specific heat capacity, thermal conductivityand ambient temperature are constants, it is possible to alter heat flux. . If the value of fade stop temperature is higher thanmaximum temperature , then fade doesn‟t occur. So for a higher fade temperature, we should have the volume of discminimum. Thus, in here we prove that fade stop temperature is higher than maximum temperature. So, theoreticallyproving fade is not possible. Advantages- Low-fade brakes such as disc brakes in steered wheels can do more brakingwithout causing brake steer, Elimination of brake fading provides a larger leverage and mechanical advantage to resist theturning of the rotor itself and It also provides a longer life time for the braking system, thus reducing the maintenance costof the vehicle
