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.

Dry and rocky

Wet and slippery

Rough and paved

19 / 30

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

The actuator starts up

The compressor stops compressing air

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

None of the above

20 / 30

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

The remove alcohol from the hydraulic master cylinder

They are optional devices that remove any amount of alcohol vapour from the air system

They add alcohol to the air brake chambers

21 / 30

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