16 / 30

What is referred to as compressed air?

When air is released into the atmosphere

When air applies the brakes

When air is pushed into a smaller space

17 / 30

All compressors run continuously...

All of these

When the engine is running

19 / 30

What's another name for the floor-mounted brake pedal?

Treadle

Pedal valve
