None of the above

It can cause the air line to be separated from the brakes

19 / 30

What happens when there is brake lining failure?

It decreases the friction surface area

Liquid oozes out of the brakes

Nothing

It causes the brake pads to cease together

20 / 30

What causes the cracks in the brake drums to widen, and eventually the drum comes apart?

Centrifugal force on the separated sections

Braking hard too often

When the brakes are pumped too often

Lack of lubricant

21 / 30

The CVSA standards require at least how much lining thickness?

3/8 inch (9.5 mm)

1/2 inch (13 mm)

1/4 inch (7 mm)

3/4 inch (19 mm)

22 / 30

What can foundation brake component failures can result in?

Demerit points

23 / 30

Within the commercial vehicle industry, what does CVSA refer to?

None of the above

24 / 30

What causes chaffed air lines?

Incorrectly secured air lines which rub on nearby parts

Defective couplers
