THE principles of the basic air brake system for trucks, trailers, and buses are reviewed in this paper. The author emphasizes especially the dual-pressure and high-pressure systems, which are able to supply air not only to the brakes, but also to other power functions.
Some additional applications are air suspension, air-powered steering, antiskid devices, transmission shifters, crane and shovel controls, and engine auxiliary controls such as air assist booster for clutch control.
