Liquid brakes in automobiles follow principle of bramha press (Pascal’s principle). What about air brakes? Collect the information about the working process of air brakes.

The working of air brakes uses many component system like engine , compressor ,Storage tank, Main Control Device ,Brake Chamber & Drum Brake.


First of all the compressor takes the power from the engine to compress the atmospheric air.


After air compression the air is stored in storage tank. It also regulates the pressure of the tank.


There exist a main control Device which regulates the pressure of air which allows to change the brake intensity.


After this the Brake chamber is their which basically converts air pressure into mechanical force. It act as return device when brake is released.


Then finally the Drum Brake creates friction ,which stops the wheels of the vehicle.


The layout of air break is given in the figure.
