50 rpm

18 / 30

If there are system failures that affect braking ability, what needs to happen?

Brake much sooner so a safe stop can be made

The vehicle must be placed out-of-service until appropriate repairs are made

Drive at a slower speed

Call your employer and ask for direction

19 / 30

What can foundation brake component failures can result in?

Demerit points

A suspended driver's license

A lot of noise

Anything from a minor application reduction to a complete failure

20 / 30

What causes chaffed air lines?

Defective couplers

A defect in the air lines

Incorrectly secured air lines which rub on nearby parts

Too much air being pushed through the lines

21 / 30

During a vehicle inspection, how do you confirm that the air tanks are securely mounted?

None of the above

Take a look at the mounts

Listen for air leaks

Push each end

22 / 30

What is the major issue of a kinked air line?

It causes reductions in brake performance by restricting or blocking the flow of air pressure

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

It stretches the air lines

None of the above

23 / 30

When does a loose air tank cause a failure?

None of the above

It doesn't

When it separates from the circuit it supplies

When the psi drop below 20 psi

24 / 30

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

Braking hard too often

Lack of lubricant

Centrifugal force on the separated sections

25 / 30
