Thick brake linings

17 / 30

Can loose brake chambers still apply some application force to the foundation brakes?

100%

Yes, depending on how loose they are

Not at all

No one knows

18 / 30

What causes the clevis pins to work their way out?

None of the above

When too much air pressure goes through the lines

Poor adjustments

When the cotter pin sheers

19 / 30

What are cracked brake drums caused by?

Old brake drums

A series of overheating and cooling

Poorly maintained brakes

Poor installation

20 / 30

What would you have to do to confirm that the brake chamber is securely installed?

Inspect the mounting fasteners and brackets

None of the above

Look on the ground for any loose pieces

Test the brakes

21 / 30

When does a loose air tank cause a failure?

It doesn't

When it separates from the circuit it supplies

When the psi drop below 20 psi

None of the above

22 / 30

What does the system leaks procedure check for?

Leaks with the air compressor

Leaks with the governor

The entire air brake system for pressure leaks through one operation

Leaks with the air lines

23 / 30

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

Call your employer and ask for direction

Drive at a slower speed

Brake much sooner so a safe stop can be made

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

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

When the brakes are pumped too often

Centrifugal force on the separated sections

25 / 30

What is the major issue of a kinked air line?
