Abstract: - As per the State Crime Records Bureau, Ministry of Road Transportation & Highway, Law commission of India, Two serious road accidents in the nation occurs every minute and 24 dies on Indian roads every hour in India. For die in every minute to brake failure. Brake pads are the most important component of an automobile decelerating system. It helps in smooth delay of a vehicle and finally bringing it to halt. Brake pads convert the vehicle's kinetic energy into thermal energy by friction. The efficiency of the brakes depends completely on frictional material used, which in turn affect the performance of the brake pads. In order to stop the vehicle or to decrease the speed of vehicle, brakes played an important role. The main component of brake which helps to stop the vehicle is brake pad, but currently most of the vehicles uses disk brake as it has high heat conductivity. Due to continuous friction of brake pad it gets injured or get wear, it may cause accidents or failure of brakes. Mostly brake failure occurs because of worn out of brake pad. To save the valued human life from those accidents happened due to failure of brake, there is a need for monitoring of braking system in automobile vehicles. Many investigates are carried out to improve the effectiveness of brake pad at the same time to display the brake pads by using several methods. In the present research paper the overview is carried out to understand the present examination on checking the brake pad and effort is made to developed new system to display the condition of brake pad.Keywords: Brake pad, Sensor Microcontroller, Light, Battery etc
