Which is not a step to test trailer service brakes?

Apply the hand valve

Ensure the trailer supply valve is closed

Release the hand valve

Gently apply engine power in a low gear

3 / 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?

Yes

Only for the primary tank

Just for the secondary tank

4 / 30

Which is not a step for testing the automatic application of the trailer spring brakes?

Pull out the trailer supply valve to close it

Listen for air exhausting, indicating application of the trailer's spring brakes

If necessary, confirm brake application by attempting to gently move the vehicle forward or backward

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

5 / 30

Brake-stroke indicators can also be fitted to what?

The pushrod

6 / 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

7 / 30

Which is not a step for testing governor operation?

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

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

Observe the primary and secondary air-tank pressure gauges

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

8 / 30

If the vehicles fails the test for measuring applied pushrod stroke, which kind of defect is it?

Minor

It just need to be noted, but not reported

Major

It's not a defect

9 / 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?

The governor is breaking down

There is no risk

12 / 30

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

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

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

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

13 / 30

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

Minor

It is not a defect

It just needs to be noted, but not reported

Major

14 / 30

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

The air brake chamber

3 psi per minute

6 psi per minute

5 psi per minute

4 psi per minute

16 / 30

Is discharging a significant quantity of moisture from the remaining air tanks, other than the supply tank normal?

Only from the secondary tank

None of the above

Yes

17 / 30

Which tank should always be drained first to prevent accumulated moisture?

The secondary tank

The supply tank

It doesn't matter

The primary tank

18 / 30

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

Or the driver is fined

Before the next inspection

Or the owner is fined

Before the vehicle can be operating again

19 / 30

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

Repaired

Open

On standby

Closed

20 / 30

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

Gently applying engine power to move the vehicle forward or backward

None of the above

Pulling in the lines

Aggressively applying engine power to move the vehicle forward or backward

21 / 30

Which is not a step to test trailer spring brakes?

Double clutch and move the vehicle forward

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

There should be no significant movement of the vehicle

Gently apply engine power in a low gear

22 / 30

Which is not a step to test tractor spring brakes?

There should be no significant movement of the vehicle

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

Gently apply engine power in a low gear

Ensure the trailer supply valve is closed

23 / 30

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

It decreases

It increases

It remains the same

It varies

24 / 30

Which is not a step to test service brakes?

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

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

Daily

Every 12 hours

26 / 30

Why do brake-stroke indicators include external reference points?

To allow the pushrod to extend
