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.

90 psi

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

16 / 30

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

Yes, depending on how loose they are

100%

Not at all

No one knows

17 / 30

What is the major issue of a kinked air line?

It stretches the air lines

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

None of the above

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

18 / 30

Why should you not mix air line fittings?

Different systems of fittings are not compatible with each other

The brakes seize up

The tractor won't respond well to the changes

They fall off

19 / 30

What causes the clevis pins to work their way out?

None of the above

When too much air pressure goes through the lines

Poor adjustments

When the cotter pin sheers

20 / 30

What does the system leaks procedure check for?

Leaks with the air compressor

The entire air brake system for pressure leaks through one operation

Leaks with the governor

Leaks with the air lines

21 / 30

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

It doesn't matter

90 rpm

50 rpm

70 rpm

22 / 30

What can foundation brake component failures can result in?

Demerit points

A lot of noise

Anything from a minor application reduction to a complete failure

A suspended driver's license

23 / 30

What causes chaffed air lines?

Too much air being pushed through the lines
