BC Air Brake Practice Test 05

When preparing to take the British Columbia air brake test, practicing with the air brake practice test is key to success. By taking the time to review and study the material, such as understanding how the air brake system works and the proper way to conduct air brake inspections, individuals can increase their confidence before taking the official exam. Not only does the practice test provide a convenient opportunity to familiarize oneself with the test format and question types, but it also helps to identify areas that may require further attention.

1 / 30

What's the purpose of the spring parking brake emergency release system?

It provides a special emergency release tank that can be used to release spring parking brakes if a disabled vehicle needs to be moved to a safe parking area and its main reservoir pressure is lost

None of the above

It provides a special emergency release tank that can be made portable

It provides a special emergency release tank that can secure spring parking brakes

2 / 30

What's the purpose of the one-way check valve?

To keep the air clean

To allow maintenance checks to be done more easily

To keep pressure built up

So the air supply in the primary and secondary reservoirs wouldn't flow backward and be lost

3 / 30

Which statement is false?

A tractor with a bobtail proportioning system will stop in a longer distance but control will be compromised

A tractor with a bobtail proportioning system will stop in a shorter distance but control will be compromised

A tractor with a bobtail proportioning system will stop in a longer distance and control will be reduced

A tractor with a bobtail proportioning system will stop in a shorter distance and control will be increased

What's the purpose of alcohol evaporators and alcohol injectors?

They are optional devices that introduce a small amount of alcohol vapour into the air system

11 / 30

What happens to the air after it passes through the dryers?

Nothing

It gets pushed to the slack adjusters

The governor needs adjustments

None of the above

16 / 30

Which statement is false? Other types of foundation brakes found on air-braked vehicles are...

17 / 30

What happens to the water vapour when the reservoir has come up to full pressure?

The compressor stops compressing air

None of the above

A purge port in the bottom of the air dryer will open and the collected contaminants are ejected along with a sudden burst of air

The actuator starts up

18 / 30

How do you know if you have an air dryer integrated system?

There will be a sticker on the front left corner of the windshield

None of the above

You can see it

The air dryer will be mounted to a small air tank

19 / 30

What's the purpose of an air dryer?

To dry the governor

To help keep the lines dry

None of the above

To remove any water vapour, oil mist and carbon particles from the air before it's delivered to the first reservoir

20 / 30

Air-over-hydraulic brakes are often found on what types of vehicles?

Tandem trailers

Middleweight trucks and buses

Tractor trailers

None of the above

21 / 30

Even if the air brake system includes an alcohol evaporator or alcohol injector, do air reservoirs still need to be drained regularly?

Yes

If asked to do so

Only if problems arise

22 / 30

Four

One

Two

Three

24 / 30
