Alberta Air Brake Test 08

Practice tests aided in building confidence and reducing test anxiety. With the knowledge gained from the practice test and dedicated study and preparation, one can approach the official exam with a higher level of assurance and increase their chances of achieving a positive outcome. Furthermore, passing the Alberta Air Brake exam is essential for aspiring commercial drivers, who must ensure the safety of themselves and others on the road.

17 / 30

What causes chaffed air lines?

Incorrectly secured air lines which rub on nearby parts

A defect in the air lines

Too much air being pushed through the lines

Defective couplers

18 / 30

What causes the cracks in the brake drums to widen, and eventually the drum comes apart?

Centrifugal force on the separated sections

Braking hard too often

When the brakes are pumped too often

Lack of lubricant

19 / 30

What are cracked brake drums caused by?

Poor installation

Poorly maintained brakes

A series of overheating and cooling

Old brake drums

20 / 30

What is the major issue of a kinked air line?

It can cause the air line to be separated from the brakes

None of the above

It stretches the air lines

It causes reductions in brake performance by restricting or blocking the flow of air pressure

21 / 30

If there are system failures that affect braking ability, what needs to happen?

The vehicle must be placed out-of-service until appropriate repairs are made

Brake much sooner so a safe stop can be made

Drive at a slower speed

Call your employer and ask for direction

22 / 30

During a vehicle inspection, how do you confirm that the air tanks are securely mounted?

Listen for air leaks

Push each end

None of the above

Take a look at the mounts

23 / 30

Air system failures are sometimes dealt with by blocking off the air lines that supply the failed component. Is this acceptable?

Never

Yes, until you get back to the yard

Only if directed by your employer

If driving at low speeds

24 / 30
