Heavy-Duty Chassis Brake and Climate Control Systems

Heavy-Duty Chassis, Brake, and Climate Control Systems explores chassis frame, suspension, and undercarriage systems utilized in on- and off-highway equipment. The course covers undercarriage wear patterns and service options on track-type equipment. Students learn how to measure undercarriage components ultrasonically and examine many different wear patterns. Students study brake theory, basic brake foundation, the antilock system, the air system, diagnostics, and servicing of heavy-duty on-highway brake systems. The course also covers air-over-hydraulic and multiple wet-disc systems used in off-highway equipment. It explores climate control as it relates to operating theory, maintenance, testing, and troubleshooting techniques of HVAC. Students learn to use testing equipment safely to diagnose and re-charge A/C systems.
