This first series reviews Air Systems. This course covers the basic functions of valves and how they relate to brake balance and wear. This class will provide the participant with the ability to identify: the charging system, primary system, secondary system and the park and emergency system. In addition, the participant will learn how to troubleshoot these systems independent of one another, diagnosing a compressor or governor problem and how the tractor and trailer air systems work together. The participant should acquire the ability to correctly identify the problem the first time and eliminate the needless replacement of components. The maintenance of Air Systems is included in this class.
