The braking system of a car is undoubtedly one of its more important feature. The aim of this work is to create a better braking system with indicator. Brake failure occurs only because of worn out of brake shoe and cut in liner.

It consists of two sensors. One sensor is connected with the brake shoe. The other sensor is the brake liner. The signal from the two sensors are given to a microcontroller. When the brake shoe is worn out, the sensor senses signal to the microcontroller.

Also if the brake liner is cut, the sensor sends signal to the microcontroller. The microcontroller analyses the signal and operates the corresponding indicator. It nothing wrong, green indicator will glow and if any one critical, red indicator will glow.

If the brake is failure in running time, an alternate brake will be operated by the microcontroller automatically. This prevents unnecessary accident.

Since this indicates the status of the brake, the user can identify the condition of the brake and thus limiting the chances of malfunction
