2. Air brake (road vehicle) - Wikipedia

   en.wikipedia.org/wiki/Air_brake_(road_vehicle)

   Truck air-actuated disc brake. An air brake or, more formally, a compressed-air-brake system, is a type of friction brake for vehicles in which compressed air pressing on a piston is used to both release the parking/emergency brakes in order to move the vehicle, and also to apply pressure to the brake pads or brake shoes to slow and stop the vehicle.

3. Railway air brake - Wikipedia

   en.wikipedia.org/wiki/Railway_air_brake

   A railway air brake is a railway brake power braking system with compressed air as the operating medium. [1] Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on April 13, 1869. [2] The Westinghouse Air Brake Company was subsequently organized to manufacture and sell Westinghouse's ...

4. Air brake (aeronautics) - Wikipedia

   en.wikipedia.org/wiki/Air_brake_(aeronautics)

   In aeronautics, air brakes or speed brakes are a type of flight control surface used on an aircraft to increase the drag on the aircraft. [1] When extended into the airstream, air brakes cause an increase in the drag on the aircraft. When not in use, they conform to the local streamlined profile of the aircraft in order to help minimize drag. [2]

5. Railway brake - Wikipedia

   en.wikipedia.org/wiki/Railway_brake

   An air brake compressor is usually capable of generating a pressure of 90 psi (620 kPa; 6.2 bar) vs only 15 psi (100 kPa; 1.0 bar) for vacuum. With a vacuum system, the maximum pressure differential is atmospheric pressure (14.7 psi or 101 kPa or 1.01 bar at sea level, less at altitude). Therefore, an air brake system can use a much smaller ...

6. S-cam - Wikipedia

   en.wikipedia.org/wiki/S-cam

   It consists of a shaft, usually around 4 to 25 inches long, turned at one end by means of an air-powered brake booster and lever with an S-shaped cam at the wheel end. Turning the shaft pushes the brake shoes against the drum, producing friction. The design allows bulky air cylinders to be located outside of the wheel.

9. Electronically controlled pneumatic brakes - Wikipedia

   en.wikipedia.org/wiki/Electronically_controlled...

   When the brake pipe and car components are charged with air, the brakes release. When the engineer needs to make a brake application, control valves in the locomotive reduce the brake pipe pressure. As the brake pipe pressure is reduced, the service portions on each car divert air from their reservoirs to their brake cylinders.
