14 / 30

To prevent the compressor from producing too much compressed air and to reduce the load on the engine, what is used in the air brake system to help?

A discharge line

A governor

A foot valve

A safety valve

15 / 30

Which are not some of the problems that can occur from the wet tank?

Moisture in the brake system remains warm and stops freezing in cold temperatures

Too much moisture and oil collecting in the air tanks can reduce the volume of air and may cause brake failure

The collected moisture and oil mixture can form a sludge that can pass from the tank into other components of the air brake system

The mixture of moisture and oil can become corrosive and damage the air tank and other system components

16 / 30

When air pressure is high enough in the system, what does the governor do?

It causes the compressor to stop pumping air

It reduces the flow of air being pumped in

It sends a warning light to the dashboard

None of the above

17 / 30

Where are the air tanks usually located?

Beside the engine

None of the above

Under or around the frame of the vehicle

Next to the cab

18 / 30

The brakes that are used for normal stopping are referred to as...

Service brakes

Main brakes

Primary brakes

Conditional brakes

19 / 30

The air that is drawn in by the air compressor contains what?

Plastic particles

Nothing

Metal fragments

Moisture

20 / 30

Do vehicles using air dryers still have the air tanks drained regularly?

Yes

Only if a problem exists

Only when inspected by a peace officer

21 / 30

The normal pressure range of an air brake system is determined by the points where the air compressor is turned off. What is this referred to as?

Turn-off pressure

Cut-out pressure

Put-out pressure

Put-in pressure

22 / 30

Moisture and oil must be drained from the tanks how often?
