1 / 30

What is added to the air brake system to help prevent moisture in the system from freezing?

Oil

Alcohol vapour

Tablets

None of the above

2 / 30

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

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

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

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

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

3 / 30

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

None of the above

It sends a warning light to the dashboard

It reduces the flow of air being pumped in

It causes the compressor to stop pumping air

4 / 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 governor

A foot valve

A discharge line

A safety valve

5 / 30

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

Service brakes

14 / 30

What can the collected moisture and oil mixture from the supply tank form?

Water

Sludge

Nothing

A solid

15 / 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?

Put-in pressure

Put-out pressure

Cut-out pressure

Turn-off pressure

16 / 30

Air compressors are generally powered directly by what?

A secondary generator

A separate battery away from the engine

Gasoline

The engine

17 / 30

Which statement is false? To avoid being in the direct path of air exhaust from the air brake system, you should be familiar with all the places where the compressed air exhausts, including...

Air-dryer exhaust port

On or near the supply tanks

Air-tank drain valves when tanks are being drained

Exhaust ports of brake valves

18 / 30

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

Metal fragments

Moisture

Nothing

Plastic particles

19 / 30

What are the primary and secondary tanks referred to as?

The dual-service tanks

The user tanks

The coupling tanks

The double tanks

20 / 30

Where are the air tanks usually located?

Next to the cab

Beside the engine

Under or around the frame of the vehicle

None of the above

21 / 30

How is the moisture drained from the tanks?

Through the air-tank drain valve

By opening up the tank and scooping it out

By vacuuming the tank

By air drying it

22 / 30

Some older vehicles are equipped with a low-air warning device near the top of the windshield that drops into the driver's view when air pressure drops. What is this?

A woggle

A toggle

A wig wag

A mig mag

23 / 30
