In the present work, it is investigated that the tremendous growth has continuously risen in demand for automobile and automotive sector. In the view of this, we need to advance our technology regarding light and heavy duty vehicles. The necessity of automatic breaking system is designed and implemented by pneumatic principle. Automatic brake with the pneumatic bumper system is an additional safety to heavy vehicles with the passenger car. It is easy to make such a system in heavy air brake vehicles. An emergency switch is provided for emergency uses.This switch avoids the driver to stand from his seat. The project carried out by us made an impressing task in the field of automobile manufacturing industries. It is very useful for the workers work in the lath and small scale industries. This project will reduce the cost involved in the concern. The project has been designed to perform the entire requirement task at the shortest time available.
