Heavy-Duty Chassis Brake and Climate Control Systems

This course will explore chassis frame, suspension, and undercarriage systems utilized in both on & off highway equipment. Undercarriage wear patterns and service options on track type equipment will be discussed. Students will learn how undercarriage components are measured ultrasonically and view many different wear patterns. This class will study brake theory along with basic brake foundation, antilock, air system, diagnostics and servicing of heavy duty on-highway brake systems. Also covered will be air over hydraulic and multiple wet disc systems used in off-highway equipment. Climate control consisting of operating theory, maintenance, testing, and troubleshooting techniques of HVAC will be explored. Students will learn to safely use testing equipment to diagnose and re-charge A/C systems.
