10-15 psi

20-25 psi

16 / 30

Air compressors are either gear driven directly from the engine or...

80-90 psi

120-145 psi

90-110 psi

Treadle

Pedal valve

20 / 30

How often must reservoirs be completely drained?

Every 12 hours

After each run

Weekly

Daily

21 / 30

How is heat generated by the brakes dissipated?

It's absorbed through the pads

By passing it off into the atmosphere

It's pushed into the air lines

It's absorbed into the tires

22 / 30

When you press down on the foot valve, air pressure enters the pressure side of the brake chamber through what?

The slack adjuster

The inlet port

The exhaust port

The spring valve

23 / 30

Although most compressors use the truck's lubrication, others are...

Not lubricated

Self-lubricated

Manually lubricated

Air lubricated

24 / 30

What is the purpose of brake chambers?

To push the compressed air into the reservoirs

To hold the brake pads

25 / 30

What is referred to as compressed air?

When air applies the brakes
