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.

12 / 30

What happens when the clevis completely separates?

The brakes cease to work when the clevis completely separates

None of the above

Missing brake linings

18 / 30

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

Listen for air leaks

Push each end

Take a look at the mounts

None of the above

19 / 30

Can loose brake chambers still apply some application force to the foundation brakes?

Not at all

Yes, depending on how loose they are

No one knows

100%

20 / 30

What happens after a plastic air line is kinked?

It is permanently damaged and must be replaced

It shortens the hose

None of the above

It takes time to unkink it

21 / 30

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

Brake much sooner so a safe stop can be made

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

Call your employer and ask for direction

Drive at a slower speed

22 / 30

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

Only if directed by your employer

If driving at low speeds

Yes, until you get back to the yard

Never

23 / 30

What causes chaffed air lines?

Too much air being pushed through the lines

Defective couplers

A defect in the air lines

Incorrectly secured air lines which rub on nearby parts

24 / 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

Lack of lubricant

When the brakes are pumped too often

25 / 30
