7 / 30

How are failures in the supply circuit recognized?

During brake failure

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

After a post-trip inspection

8 / 30

What's the purpose of the slack adjuster?

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

Full-automatic couplers

None of the above

Dead-end couplers

10 / 30

What is the problem with air pressure park brakes?

They are not as tight as spring brakes

Not enough pressure to park

None of the above

Air pressure drains out of the system, the park brakes will release

11 / 30

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

1/2 inch (13 mm)

1/4 inch (7 mm)

3/8 inch (9.5 mm)

3/4 inch (19 mm)

12 / 30

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

Pull the trailer supply valve

Pump the pedal

Apply the park brakes

Downshift

13 / 30

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

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

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

14 / 30

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

None of the above

Secondary service circuit failure

Emergency brake failure

Primary service circuit failure

15 / 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?

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

The driver will know if lines were crossed

The secondary tank is low in air pressure

The primary tank is low in air pressure

16 / 30

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

Apply the mechanical brakes

Pull the trailer air supply valve

Take a longer route to stop the vehicle

Pump the brakes

17 / 30

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

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

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

Blow into the couplers

Nothing

18 / 30

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

The employer receives a ticket

The vehicle will be placed out-of-service

The vehicle must return to the yard

The driver receives a ticket

19 / 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

No reason

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

It's the straightest path

20 / 30

What does the service/control line do?

None of the above

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

Blocks the control system

Disconnects the trailer service relays

21 / 30

When would the dash park control valve be used?

Overnight parking

Poor road conditions

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

Parking on a grade

22 / 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

23 / 30

What do glad hand couplers do?

Connects the air lines to the cylinders

Connects the air lines to the trailer

None of the above

Connects the air dryer to the air lines

24 / 30

During emergency braking, which statement is false?

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

Monitoring air pressure gauges for proper operation

Pump the brake pedal until air builds up in the lines

Hold a steady brake application to avoid additional loss of air

25 / 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 tough to attach to the trailers

They become brittle over time

26 / 30

What does the tractor protection valve do?

Closes off the service line

Controls the supply line

Uses supply line pressure to open the service line

Stops air pressure from entering the lines

27 / 30

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

Yes

Only if towing tandem trailers

Straight trucks only

28 / 30

During a secondary service circuit failure, which brakes will not apply?

29 / 30

What will enforcement officers during Level 1 Commercial Vehicle Safety Alliance (CVSA) inspection will check?

The psi of the primary tank

Both parts of the tractor's protection system

The psi of the secondary tank

30 / 30

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

Most of the air supply

All of the air supply only
