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.

7 / 30

What are cracked brake drums caused by?

Old brake drums

A series of overheating and cooling

9 / 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

10 / 30

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

Yes, depending on how loose they are

11 / 30

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

Anything from a minor application reduction to a complete failure

15 / 30

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

None of the above

Inspect the mounting fasteners and brackets

Test the brakes

16 / 30

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

17 / 30

What happens when the clevis completely separates?

The brakes cease to work when the clevis completely separates

The brakes begin to squeal

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

The brakes can lock

18 / 30

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

It doesn't matter

Certified heavy equipment technicians

Anyone on the maintenance team

The driver

19 / 30

What happens after a plastic air line is kinked?

It takes time to unkink it

It is permanently damaged and must be replaced

None of the above

It shortens the hose

20 / 30

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

The lines to the park brake

The lines leading up to the compressor

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

None of the above

21 / 30

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

80 rpm

120 rpm

100 rpm

60 rpm

22 / 30

With regard to brake lining, what causes oil saturation?

Oil from the asphalt

Leaking couplers

Leaking wheel seals

None of the above

23 / 30

Why should you not mix air line fittings?

The brakes seize up

The tractor won't respond well to the changes

Different systems of fittings are not compatible with each other

They fall off

24 / 30

What causes chaffed air lines?

A defect in the air lines

Defective couplers

Incorrectly secured air lines which rub on nearby parts

Too much air being pushed through the lines

25 / 30

What causes hose bulges within the air lines?

Debris in the air lines

Too much air being pushed through the lines

Defective couplers

Internal structure failure or excessive chaffing
