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.

15 / 30

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

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

It stops over-filling of the reservoirs

It keeps the air flowing to the brake chambers

16 / 30

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

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

Any time the brakes do not function properly

17 / 30

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

For tandem trailers

For use on dual-air system vehicles

19 / 30

What is the purpose of the air dryer?

It helps to keep the inside of the compressor working efficiently

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

It dries the air as it reaches the brake chambers

It keeps the hoses clean

20 / 30

Where is the one-way check valve installed?

In front of the compressor

Next to the governor

Under the foot valve

Between the supply and service reservoirs

21 / 30

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

Cut-in

Cut-out

Pushes

Presses
