21 / 30

Will the reservoirs be able to store a sufficient volume of air to allow several brake applications if the engine stops or the compressor fails?

Depending on the number of reservoirs

Yes

Depending on the size of the reservoirs

22 / 30

Do all compressors run continuously while the engine is running?

24 / 30

What is referred to as a diaphragm?

A small port
