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.

Through the rotors

Through the air dryers

17 / 30

When the park control valve is pulled, what happens?

It prepares the brakes to application

None of the above

Air is exhausted and the park spring expands and applies the foundation brake

The park brakes are released

18 / 30

Which statement is false? During a brake application...

19 / 30

How much full-service brake applications should the air tank volume capacity be capable of providing?

A minimum of 12 full-service brake applications for power units and 8 full-service applications for trailers

a minimum of 10 full-service brake applications for power units and 10 full-service applications for trailers

A minimum of 8 full-service brake applications for power units and 12 full-service applications for trailers

22 / 30

What is the purpose of a check valve?

None of the above

It checks that the hoses are running smoothly

It checks the service tanks for air

It protects the service tanks from air supply failure

23 / 30

What do brake chambers do?

Houses the brakes until they are needed

None of the above

Hold the air to be used for the brakes
