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.

15 / 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

16 / 30

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

Push each end

Take a look at the mounts

None of the above

None of the above

When it separates from the circuit it supplies

It doesn't

18 / 30

What is the maximum air pressure leakage allowable during the air systems leaks procedure?

4 psi loss per service circuit for power units

3 psi loss per service circuit for power units

19 / 30

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

Drive at a slower speed

Brake much sooner so a safe stop can be made

Call your employer and ask for direction

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

20 / 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

Never

Yes, until you get back to the yard

If driving at low speeds

21 / 30

What would you have to do to confirm that the brake chamber is securely installed?

Test the brakes

None of the above

Inspect the mounting fasteners and brackets

Look on the ground for any loose pieces

22 / 30

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

Braking hard too often

Lack of lubricant

When the brakes are pumped too often

Centrifugal force on the separated sections

23 / 30

What causes the clevis pins to work their way out?

Poor adjustments

When too much air pressure goes through the lines

When the cotter pin sheers

None of the above

24 / 30

What is the major issue of a kinked air line?

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

None of the above

It stretches the air lines

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