Depending on the size of the reservoirs

Depending on the number of reservoirs

Yes

15 / 30

What is the purpose of brake shoes and drums or brake rotors and pads?

To house the braking components

18 / 30

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

The wheels stop turning

The spring brakes activate

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

None of these

19 / 30

Do all compressors run continuously while the engine is running?

Yes

Only when the rpm is above 1200

Only when the compressor switch is in the on position

20 / 30
