Alberta Air Brake Test 03

Taking the Alberta Air Brake practice test is essential to obtaining the required certification to operate vehicles equipped with air brakes. Not only does the practice test help you gauge your knowledge, but it also helps you prepare for the official exam. It is a means to identify gaps in your understanding and provides an opportunity to rectify them. Carrying out ample practice can help you pass the exam with flying colors.

When air pressure in the brake chambers exhausts through the quick release valve

When the chambers are not full of air

18 / 30

What does air brake antifreeze essentially do?

Nothing

To prevent rubber components in the valves from drying out

To keep the air hoses from freezing

To prevent the air from freezing

19 / 30

What do brake chambers do?

None of the above

Convert air pressure into mechanical force

Houses the brakes until they are needed

Hold the air to be used for the brakes

20 / 30
