Alberta Air Brake Test 04

Studying the Alberta Driver’s Guide and the Air Brake Manual is recommended. Mastering the concepts of air brakes, including their main components, signs of brake failure, and maintenance schedules, is crucial.

Pull the trailer supply valve

Apply the park brakes

Downshift

Pump the pedal

7 / 30

What do the air lines that connect to the trailer carry?

Hydraulic fluid

All of the air supply only

The air supply and the brake signal to the trailer service and park circuits

Most of the air supply

8 / 30

What can you do to remove contamination before attaching the glad hand couplers?

Nothing

Blow into the couplers

Shake the couplers for 10 seconds each before connecting the glad hand couplers to shake the contamination out

A quick discharge of air pressure before connecting the glad hand couplers to blow contamination out

9 / 30

Having a very powerful emergency brake, twice as powerful as spring park brakes, what is the risk?

Having a load shift in an emergency

Brake lockup in an emergency application

Brake failure on the tractor

Brake failure on the trailers

10 / 30

What is the minimum lining thickness for brake linings from the Commercial Vehicle Safety Alliance (CVSA) roadside inspection out-of-service criteria?

3/8 inch (9.5 mm)

1/4 inch (7 mm)

1/2 inch (13 mm)

3/4 inch (19 mm)

11 / 30

How are failures in the supply circuit recognized?

The air pressure gauges not replenishing when the air pressure gets below the governor cut-in level

During pre-trip inspections

After a post-trip inspection

During brake failure

12 / 30

What will cause the glad hand couplers to leak?

If the air pressure is too much

If the seals are soft or degraded

If the couplers are not attached securely

If the seals are the wrong size

13 / 30

What does the service/control line do?

None of the above

Blocks the control system

Carries the control system from the foot valve to the trailer service circuit relays

Disconnects the trailer service relays

14 / 30

Foundation brakes are the mechanical component at the axle ends. If they are not working properly, what happens?

The driver should apply the park brakes

The driver will need to use the emergency brakes to stop the vehicle

The driver should find a place to come to a safe stop

The air brake system will not be able to stop the vehicle

15 / 30

What's the purpose of the slack adjuster?

It automatically adjusts the slack in the brake lines

It converts push rod force from the chamber to torque on the s-cam shafts

It forces the air intake valve

None of the above

16 / 30

Why do flat deck haulers run the trailer air lines from the back of the frame to the landing leg area of the trailer, rather than from the back of the cab to the nose of the trailer?

It's the shortest path

Causes less interference from loads that overhang the front of the deck

It's the straightest path

No reason

17 / 30

What can become a problem of a tractor using coiled plastic air lines?

They are often too short and will stretch, causing the lines to shrink in diameter

Nothing

They become brittle over time

They become tough to attach to the trailers

18 / 30

Is the trailer supply valve part of the tractor's protection system?

Only if towing tandem trailers

Straight trucks only

Yes

19 / 30

Pushing in the trailer air supply valve (red button) with the park control valve (yellow button) pulled during these vehicle inspections will allow what to happen?

The primary tank is low in air pressure

Any air leaks to be noticed and dealt with before the equipment is put into service

The secondary tank is low in air pressure

The driver will know if lines were crossed

20 / 30

If the trailer does lose traction during a trailer supply line failure, what happens?

The trailer will swing

The ABS will activate

None of the above

It will take three times as long to stop in a straight line

21 / 30

What is the only tractor air system failure that will cause a service circuit's brakes not to work during a service application?

Emergency brake failure

Secondary service circuit failure

None of the above

Primary service circuit failure

22 / 30

If the trailer service brakes are not working and the vehicle must be stopped quickly, what should the driver do?

Take a longer route to stop the vehicle

Apply the mechanical brakes

Pump the brakes

Pull the trailer air supply valve

23 / 30

When would the dash park control valve be used?

Overnight parking

Any situation where there is a loss of service brakes and a quick stop is required

Parking on a grade

Poor road conditions

24 / 30

If there is any doubt about the security of the glad hand couplers during coupling, pre-trip and en-route inspections, what should happen?

The Inform your employer

Drive with caution until more evidence is gathered

Add it to the report

Repairs must be made immediately

25 / 30

During emergency braking, which statement is false?

Pump the brake pedal until air builds up in the lines

Monitoring air pressure gauges for proper operation

Hold a steady brake application to avoid additional loss of air

When safely stopped, the vehicle should not be driven until repairs are completed

26 / 30

During a roadside inspection, what happens if the trailer air supply valve does not work properly?

The employer receives a ticket

The vehicle must return to the yard

The driver receives a ticket

The vehicle will be placed out-of-service

27 / 30

What should glad hand couplers have on them when not pulling a trailer?

Full-automatic couplers

Semi-automatic couplers

None of the above

Dead-end couplers

28 / 30

What does the tractor protection valve do?

Controls the supply line

Closes off the service line

Uses supply line pressure to open the service line

Stops air pressure from entering the lines

29 / 30

Rather than using mechanical spring park brakes to hold the foundation brakes on for the emergency brake, what can be done instead?

Nothing can be done

Increase the diameter of the air hoses

Air from the service tank is supplied to the service chambers

Increase the size of the brake pads

30 / 30

What year did were spring park brakes required on trailers?

1976

1996
