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.

None of the above

4 / 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

Call your employer and ask for direction

Drive at a slower speed

Brake much sooner so a safe stop can be made

5 / 30

What does the system leaks procedure check for?

9 / 30

When does a loose air tank cause a failure?

When the psi drop below 20 psi

It doesn't

None of the above

When it separates from the circuit it supplies

10 / 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

Never

Yes, until you get back to the yard

11 / 30

What causes the clevis pins to work their way out?

13 / 30

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

Braking hard too often

Centrifugal force on the separated sections

Lack of lubricant

When the brakes are pumped too often

14 / 30

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

4 psi loss per service circuit for power units

2 psi loss per service circuit for power units

5 psi loss per service circuit for power units

3 psi loss per service circuit for power units

15 / 30

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

100%

Not at all

No one knows

Yes, depending on how loose they are

16 / 30

What causes chaffed air lines?

Defective couplers

A defect in the air lines

Incorrectly secured air lines which rub on nearby parts

Too much air being pushed through the lines

17 / 30

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

Test the brakes

Look on the ground for any loose pieces

None of the above

Inspect the mounting fasteners and brackets

18 / 30

Which of the following is not included in the air supply circuit inspection?

The air dryer

The governor

The low air pressure warning device

The air compressor

19 / 30

What can foundation brake component failures can result in?

A lot of noise

Demerit points

Anything from a minor application reduction to a complete failure

A suspended driver's license

20 / 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

21 / 30

To check the air compressor, run the engine at 1200 rpm and stop the timing when the air pressure is at what rpm?

140 psi

It doesn't matter as long as it's been running for six minutes

120 psi

90 psi

22 / 30

What happens when the clevis completely separates?

The brakes lose power and takes a longer distance to stop the vehicle

The brakes can lock

The brakes cease to work when the clevis completely separates

The brakes begin to squeal

23 / 30

What happens after a plastic air line is kinked?

It is permanently damaged and must be replaced

It shortens the hose

It takes time to unkink it
