19 . Most heavy-duty vehicles use:
Quadruple air brake systems.

20 . If one air system in a dual air brake system is very low on pressure:
Lights on the outside of the tractor will flash.
In a dual air brake system, if one of the air systems gets very low on pressure, either the front or rear brakes will not be operating fully. You should bring your vehicle to a safe stop and have the air system repaired.

The total stopping distance for vehicles equipped with air brakes is made up of four factors: perception distance, reaction distance, brake lag distance, and braking distance. When braking at a speed of 55 mph while driving on dry pavement, the brake lag can add around 32 feet to a vehicle's total stopping distance.
22 . Foundation brakes are used:

Foundation brakes are used at each wheel. The most common type is the S-cam drum brake.
23 . Failing to drain the tanks in an air brake system can result in:

24 . A low air pressure warning signal should activate:
When tank pressure falls below 5 psi.
In an air brake system, a low air pressure warning signal must come on if air pressure in the tanks falls below 55 psi. This warning signal may come in the form of a light, a buzzer, or a wig wag.

A tool to improve fuel efficiency.
As long as the brakes are properly maintained, using air brakes is a safe and effective method of stopping large, heavy vehicles.
