1 . If an air compressor is belt-driven, the belt should be routinely checked to ensure that it is:

Thin.

Properly tightened.

Cracked.

If your vehicle has air brakes, the air compressor drive belt should be checked before each drive. Check the tightness of the belt and verify that it is in good condition.

2 . During an applied leakage test, what is the maximum leakage rate that is safe for a single vehicle with air brakes?

10 psi in one minute

5 psi in one minute

3 psi in one minute

It is important to know the maximum air loss rate that is safe for your specific vehicle. A single vehicle with air brakes should have a leakage rate no higher than 3 psi in a minute during an applied leakage test.

3 . Air tank drains:

Should not be used in cold weather.

Are helpful to remove water and oil from the air tanks.

Are used to move air to the brakes.

Compressed air in an air brake system usually has a certain amount of water and oil in it. This can harm the system if allowed to accumulate. Air tanks have drain valves to aid in removing water and oil from the compressed air.

4 . What is removed when an air tank is drained?

Water and oil

Ammonia

Liquid cleaners

In an air brake system, air tanks have drains to remove accumulations of water and compressor oil. Allowing water and oil to accumulate in the system could cause damage to the brakes.

5 . What kind of brakes do most newer heavy-duty trucks use?

Single air brakes

Dual air brakes

Triple air brakes

Most newer heavy-duty vehicles use dual air brake systems. A dual air brake system has two separate air brake systems which use a single set of brake controls.

6 . To affect a vehicle, ABS:

Must be on all axles.

Must be on the rear axle.

Can be on as few as one axle.

Anti-lock brakes on only a single axle still provides a driver with more control while braking than they would have without any anti-lock brakes.
