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

What causes the clevis pins to work their way out?

16 / 30

What happens after a plastic air line is kinked?

None of the above

It is permanently damaged and must be replaced

It shortens the hose

It takes time to unkink it

17 / 30

What causes chaffed air lines?

A defect in the air lines

Too much air being pushed through the lines

Defective couplers

Incorrectly secured air lines which rub on nearby parts

18 / 30

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

Anyone on the maintenance team

The driver

Certified heavy equipment technicians

It doesn't matter

19 / 30

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

60 rpm

100 rpm

80 rpm

120 rpm

20 / 30

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

Push each end

None of the above

Listen for air leaks

Take a look at the mounts

21 / 30

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

Never

Yes, until you get back to the yard

If driving at low speeds

Only if directed by your employer

22 / 30

What does the phrase 'cammed over' refer to?

Missing brake linings

None of the above

Thick brake linings

Excessively worn brake linings

23 / 30

With regard to brake lining, what causes oil saturation?

Leaking wheel seals

Oil from the asphalt

None of the above

Leaking couplers

24 / 30

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

70 rpm

90 rpm

50 rpm

It doesn't matter

25 / 30

What are cracked brake drums caused by?

Poor installation

A series of overheating and cooling

26 / 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

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