This module describes how compressed air is produced and stored in the supply subsystem and the main vehicle components involved. It also outlines vehicle safety features for regulating and monitoring air pressure, and the air pressure safety standards vehicles must meet. After completion, participants will be able to:
- List each major component of the supply subsystem and describe its function
- Monitor air pressure and identify abnormalities in the air brake system
- Describe vehicle safety features that respond to air pressure abnormalities
