1 . Air brakes are:
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.
2 . A vehicle equipped with an Anti-Lock Braking System (ABS) uses a ____ light to warn that the system is not working properly.
White
Anti-Lock Braking System (ABS) malfunction lamps are usually yellow. Even if the ABS isn't working properly, a driver will still have access to the vehicle's usual braking functions.
3 . The safety valve located on the first tank opens:
After every stop.
In an air brake system, the first tank that receives compressed air has a safety valve that releases air if the pressure gets too high. It is usually set to open at 150 psi. If the valve must open, there is a fault in the system that should be repaired by a mechanic.
4 . Failing to drain the tanks in an air brake system can result in:
Too much fuel being carried.
In an air brake system, the air storage tanks must be drained to remove accumulated water and compressor oil. Failing to do this can cause damage. For example, water that has built up in the system could freeze in cold weather and cause brake failure.
5 . Brakes may get out of adjustment:
If they get wet.
Brakes can get out of adjustment quickly, especially if they are used to the point of overheating. Brake adjustment should be checked frequently.
6 . On newer vehicles, how do you put on the parking brake?
Pull up on the steering column.
On newer vehicles with air brakes, the parking brake is controlled by a yellow, diamond-shaped knob. The knob is pulled out to set the brakes, and pushed in to release them.
