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. Braking distance - Wikipedia

   en.wikipedia.org/wiki/Braking_distance

   Braking distance refers to the distance a vehicle will travel from the point when its brakes are fully applied to when it comes to a complete stop. It is primarily affected by the original speed of the vehicle and the coefficient of friction between the tires and the road surface, [Note 1] and negligibly by the tires' rolling resistance and vehicle's air drag.

   Exhaust brakes are simpler in operation than an engine brake.Essentially, the exhaust pipe of the vehicle is restricted by a valve.This raises the pressure in the exhaust system, forcing the engine to work harder on the exhaust stroke of its cylinders, so again the engine is acting as an air compressor, with the power required to compress the air being withheld from the exhaust pipe, retarding ...

6. Brake tester - Wikipedia

   en.wikipedia.org/wiki/Brake_tester

   A roller brake tester is a method of allowing the dynamic assessment of the braking system of a motor vehicle, whilst the vehicle itself is in a static condition.This type of brake tester is normally used in UK garages when used as part of an inspection lane for the MOT test.

7. Westinghouse Air Brake Company - Wikipedia

   en.wikipedia.org/wiki/Westinghouse_Air_Brake_Company

   Working conditions at the Westinghouse Air Brake Company (WA&B) were more than adequate, and the company instituted new policies for its employees. For example, in 1869, it was one of the first companies to institute a 9-hour work day and a 55-hour work week, at a time when typical working days spanned between 10 and 12 hours (and sometimes ...
