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.

1 / 30

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

Yes, until you get back to the yard

Never

If driving at low speeds

Only if directed by your employer

2 / 30

What can foundation brake component failures can result in?

Demerit points

A suspended driver's license

A lot of noise

Anything from a minor application reduction to a complete failure

3 / 30

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

5 psi loss per service circuit for power units

4 psi loss per service circuit for power units

3 psi loss per service circuit for power units

2 psi loss per service circuit for power units

4 / 30

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

Drive at a slower speed

Call your employer and ask for direction

Brake much sooner so a safe stop can be made

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

5 / 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%

6 / 30

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

8 / 30

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

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

120 psi

140 psi

90 psi

9 / 30

Why should you not mix air line fittings?

They fall off

Different systems of fittings are not compatible with each other

10 / 30

What is the major issue of a kinked air line?

None of the above

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

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

It stretches the air lines

11 / 30

What causes hose bulges within the air lines?

Too much air being pushed through the lines

Debris in the air lines

Internal structure failure or excessive chaffing

12 / 30

To check the air compressor, run the engine at 1200 rpm, the low-pressure warning should go out at what rpm?

60 rpm

120 rpm

80 rpm

100 rpm

13 / 30

If there are any corrosion or damage seen in brake chambers or clamp rings, who is qualified to repair it?

The driver

It doesn't matter

Anyone on the maintenance team

Certified heavy equipment technicians

14 / 30

What happens when the clevis completely separates?

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

The brakes begin to squeal

The brakes can lock

The brakes cease to work when the clevis completely separates

15 / 30

What does the system leaks procedure check for?

Leaks with the governor

Leaks with the air lines

Leaks with the air compressor

The entire air brake system for pressure leaks through one operation

16 / 30

What happens after a plastic air line is kinked?

None of the above

It takes time to unkink it

It shortens the hose

It is permanently damaged and must be replaced

17 / 30

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

Inspect the mounting fasteners and brackets

Look on the ground for any loose pieces

None of the above

Test the brakes

18 / 30

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

90 rpm

70 rpm

It doesn't matter

50 rpm

19 / 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

20 / 30

What causes chaffed air lines?

Incorrectly secured air lines which rub on nearby parts

Defective couplers

A defect in the air lines

Too much air being pushed through the lines

21 / 30

What does the phrase 'cammed over' refer to?

Thick brake linings

None of the above

Missing brake linings

Excessively worn brake linings

22 / 30

What happens when there is brake lining failure?

Liquid oozes out of the brakes

Nothing

It decreases the friction surface area

It causes the brake pads to cease together

23 / 30

When does a loose air tank cause a failure?

None of the above

When it separates from the circuit it supplies

It doesn't

When the psi drop below 20 psi

24 / 30

What is the only air line not filled during this air systems leaks procedure?

The lines leading up to the compressor

The lines to the park brake

None of the above

The control line from the hand valve to the double check valve

25 / 30

The CVSA standards require at least how much lining thickness?

1/4 inch (7 mm)

3/8 inch (9.5 mm)

1/2 inch (13 mm)

3/4 inch (19 mm)

26 / 30

What causes the clevis pins to work their way out?

When the cotter pin sheers
