It is not a defect

Minor

It just needs to be noted, but not reported

Major

23 / 30

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

The secondary tank

It doesn't matter

The primary tank

The supply tank

24 / 30

Why do brake-stroke indicators include external reference points?

To allow the pushrod to extend

To provide a physical block to shorten the stroke

To provide an audible indication of the applied pushrod stroke

To provide a visual indication of the applied pushrod stroke

25 / 30
