Saskatchewan Air Brake Test 03

If you’re interested in obtaining your Saskatchewan Air Brake endorsement, it’s essential to prepare for the official exam thoroughly. One of the best ways to do so is by taking the free practice test that Saskatchewan Government Insurance (SGI) offers. Not only will this test provide you with a comprehensive understanding of the kind of questions you’ll encounter on the actual exam, but it will also help you identify any areas you might need to work on further.

7 / 30

What determines the amount of heat that can be absorbed and dissipated to the atmosphere?

The size of the shoes

The number of brake chambers

The size of the brake chambers

Drum thickness

8 / 30

What is installed near the rear brake chambers to correct brake lag?

Nothing

9 / 30

Which statement is false? Several additions can be made to the basic system to improve it, including...

Low warning switch

Rear-brake limiting valve

Air pressure gauge

service reservoir

10 / 30

Which statement is false? To alert you when air pressure drops below a safe level, the following is installed...

A low air warning buzzer

A low air warning bell

A low air warning light

A low air warning wig-wag

11 / 30

What should you do if the low air warning system activates?

Remove half your load so your vehicle is lighter

Drive at a slower speed

Continue to drive but place your hazard light on

You must stop and determine the cause

12 / 30

What is the ratio valve designed for?

All of these

For use on dual-air system vehicles

For tandem trailers

For heavy load vehicles

13 / 30

Air pushes against each service-brake diaphragm causing what to happen?

The push rod to move the slack adjuster

The can shaft to secure

The return spring to move

All of these

14 / 30

The first reservoir is closest to the compressor it is now called...

The main reservoir

The service reservoir

The premier reservoir

The supply reservoir

15 / 30

Why do front brake assemblies have the brake chamber and slack adjuster mounted on the backing plate?

It improves fuel economy

Because the steering action of the front axle would otherwise interfere

It improves the suspension

All of these

16 / 30

What happens when reservoir air pressure drops?

The spring brakes activates to apply brake pressure

The brake chambers force more pressure onto the brake system

The warning system activates

The governor puts the compressor back into the pumping stage to keep adequate air pressure available for future brake applications

17 / 30

What's the purpose of a one-way check valve?

It stops over-filling of the reservoirs

It keeps the air flowing to the brake chambers

It stops the air from over-filling the brake chambers

To keep air from bleeding back from the supply to the service reservoir

18 / 30

The stop light switch is an air-signaled electrical switch which is turned on...

Any time the brakes do not function properly

Manually when the driver applies pressure to stop the trailer

Any time a brake application is made

Any time the brakes have stopped the wheels from rotating

19 / 30

What is A low-pressure warning device that drops into driver view called?

Mig-mag

Big-wag

Dig-mag

Wig-wag

20 / 30

This safety valve is pre-set, usually at what pressure?

150 psi

125 psi

110 psi

21 / 30

Where is the ratio valve installed?

In the front axle delivery line

Behind the compressor

Next to the governor

In front of the supply tank

22 / 30

The supply reservoir is protected from being over-pressurized and bursting by what?

A shut-off valve

A safety valve

A one-way valve

A pressure valve

23 / 30

Which statement is false? The following will result in erratic, unpredictable and potentially dangerous brake performance.

Thin or distorted drums

Improper linings

Adjusted spring adjustors

Weak return springs

24 / 30

What is the purpose of the air dryer?

It keeps the hoses clean

It removes most liquid and water vapour from compressor discharge air before it reaches the air brake reservoirs

It helps to keep the inside of the compressor working efficiently

It dries the air as it reaches the brake chambers

25 / 30

If a safety valve blows off excess pressure, what does this mean?

The air hoses are too big

The reservoirs are too large

Not enough reservoirs

A problem with the governor

26 / 30

The second reservoir is called...

The supply reservoir

The service reservoir

The secondary reservoir

The primary reservoir

27 / 30

Older trucks may be equipped with a front wheel limiting valve controlled by what?

A switch on the dash

Automatically by the air system

None of these

A foot valve

28 / 30

Do air dryers remove all moisture?

Most of the air hoses

Depending on the size of the dryer

Yes

29 / 30

What is another name for when the governor starts the compressor into its pumping stage?
