• Air Brakes (a.k.a. pneumatic brakes/harsh brake) are predominantly used on medium and heavy duty commercial vehicles having much higher braking torque requirements.
• Air brakes are more effective and are actuated faster with shorter braking distances.
• This is the reason why heavy commercial vehicles are fitted with sign boards reading “Caution …

An air or pneumatic braking system is used in medium & heavy duty vehicles. This system has following advantages:
i) The pressure on the pre-compressed air allow any force regulate for braking to developed very small effort applied by the driver to the brake pedal.
ii) The compressed air can …
