Yes

Only from the secondary tank

3 / 30

If the vehicle fails the test for system air-loss, it must be reported to the operator and repaired...

Before the next inspection

Before the vehicle can be operating again

Or the driver is fined

Or the owner is fined

It's not a defect

Minor

Major

It just need to be noted, but not reported

The hexagon ports

The round ports

6 / 30

Which is not a step to test service brakes?

Apply the service brakes and ensure the brake application stops the vehicle

Ensure the trailer supply valve is open and release the tractor spring parking brakes

Ensure the trailer supply valve is closed

Move the vehicle forward in a low gear and at a slow speed

7 / 30

To determine whether brake adjustment is correct, the pushrod stroke must be inspected how often?

Every 8 hours

Every 36 hours

Every 12 hours

Daily

8 / 30

Opening the trailer supply valve to fully charge the trailer, then pull out the trailer supply valve to close I so the trailer spring brakes should apply. What else does this?

Disconnecting the trailer emergency line

Disconnecting the trailer air-supply line

Disconnecting the trailer discharge line

Nothing

9 / 30

Which is not a step to test trailer service brakes?

Ensure the trailer supply valve is closed

Gently apply engine power in a low gear

Apply the hand valve

Release the hand valve

10 / 30

Which statement is false? Long-stroke brake chambers can be identified by these visible characteristics...

The air lines attach to a hexagon port in the brake chamber body.

Markings are placed on the brake chamber body to indicate that it is a long-stroke brake chamber

The air lines attach to a square port in the brake chamber body

A trapezoidal tag is placed under the clamp bolt that indicates the brake chamber's maximum stroke dimension

11 / 30

To test the automatic application of the trailer spring brakes, brake application may be confirmed by doing what?

None of the above

Aggressively applying engine power to move the vehicle forward or backward

Gently applying engine power to move the vehicle forward or backward

Pulling in the lines

12 / 30

Which is not a step for testing governor operation?

Run the engine until air brake system pressure reaches its maximum level and note the cut-out pressure setting

Release the chocks from the vehicle and release the tractor spring brakes

Observe the primary and secondary air-tank pressure gauges

Fan the brakes to lower the system pressure and note the cut-in pressure setting

13 / 30

Which is not a step to test tractor spring brakes?

Ensure the trailer supply valve is open and the tractor spring brakes are applied

Ensure the trailer supply valve is closed

Gently apply engine power in a low gear

There should be no significant movement of the vehicle

14 / 30

To test the tractor protection valve, the trailer supply valve must be...

On standby

Open

Repaired

Closed

15 / 30

When testing system air-loss for a tractor and trailer, what is the maximum allowable air loss?

3 psi per minute

4 psi per minute

6 psi per minute

5 psi per minute

16 / 30

Why do brake-stroke indicators include external reference points?

To provide a physical block to shorten the stroke

To allow the pushrod to extend

To provide a visual indication of the applied pushrod stroke

To provide an audible indication of the applied pushrod stroke

17 / 30

Which is not a step to test trailer spring brakes?

Double clutch and move the vehicle forward

There should be no significant movement of the vehicle

Close the trailer supply valve and release the tractor spring brakes.

Gently apply engine power in a low gear

18 / 30

Which is not a step to test the air tank drain valves?

Ensure that the air brake system is below its normal operating pressure range

Locate and drain the supply tank until the valve discharges only clean air

Locate and drain the remaining air tanks

Watch the discharge from each air tank and ensure that all air tank drain valves function properly

19 / 30

If the vehicle fails the test when testing the air-tank drain valves, what kind of defect is it?

Major

Minor

It just needs to be noted, but not reported

It is not a defect

20 / 30

As the brakes wear, what happens to the brake pushrod stroke?

It remains the same

It varies

It decreases

It increases

21 / 30

When there is a sudden increase in the amount of moisture or oil drained from any tank, does the condition have to be reported?

Only for the primary tank

Yes

Just for the secondary tank

22 / 30

Brake adjustment limits vary depending on the size and type of what?

The air brake chamber

The vehicle

The pushrod size

The slack adjuster

23 / 30

When inspecting the brake adjustment, what should the air pressure be?

Above 110 psi

Above 90 psi
