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.

23 / 30

Does every axle group will have an independent service brake circuit?

Some do

Yes

Just the last axle group

24 / 30

It's not recommended to take park springs apart. Why is this?

Only the top mechanical team could do this

It's too tough a job

No reason

There are no repairable parts inside

25 / 30

To reduce lag time, what is installed near the brake chambers?
