16 / 30

What is the purpose of a governor?

It loads or unloads the compressor

22 / 30

Should compressors that have their own filtration system be serviced on a regular basis?

Only if directed by a service technician

Only if a warning light shows up on the dashboard

Yes

23 / 30

25 / 30

How is heat generated by the brakes dissipated?

It's absorbed into the tires

It's absorbed through the pads

It's pushed into the air lines

By passing it off into the atmosphere

26 / 30

What happens when air pressure is released from the service-brake chamber?

None of these

The spring brakes activate

The wheels stop turning

The return spring returns the diaphragm and push rod to their released positions

27 / 30
