2) How is a plugged air filter likely to effect the compressor?<br />
3) What causes moisture to form in the air brake system?<br />
4) When is the compressor able to accomplish most of its cooling?<br />
5) How often must reservoirs be drained?<br />
6) What is the maximum air pressure available for a brake application at any given time?<br />
