ABSTRACT: One of the most important safety features in an automobile is brake. A typical automobile consists of two types of brakes, one for retarding the speed of vehicle while it is in motion and other is to hold the vehicle in its place when standing still or parked. Due to operator errors the conventional handbrake system remained engaged even when the vehicle was moving due to manual operation of the hand lever through which the handbrake is operated. This led the brakes to become ineffective and eventually they failed to serve their purpose. To overcome all the limitation of the conventional system we are using automatic handbrake engagement and release system. This system uses electro-pneumatically operated components using solenoid and pneumatic circuits. Hand brake is one of the most important component in vehicles. Conventional handbrake system works using a ratchet locking mechanism that will keep it engaged until a release button is pressed. Driver error can lead to accidents in which handbrake is not engaged. To overcome this, an Automatic Hand Brake engaging and disengaging system is proposed. The hand brake engagement and disengagement is done using a combination of rack & pinion arrangement and Solenoid Valve controller. An automatic brake system for a vehicle consists of an electric motor, related to the motor for transmission motion from the motor to a brake lever that pushes the restraint. This project provides a brand new idea style of the pneumatic parking brakes system that has straightforward and cheap characteristics. This project deals with coming up with and fabrication of pneumatic braking system.
