This module covers the operation and function of the service brake subsystem. It explains the journey that compressed air takes from the brake pedal to the brake chambers and how it is converted into mechanical braking force. The importance of brake adjustment is also covered. After completion, participants will be able to:
- Explain what happens when you press the brake pedal
- List brake valves that assist in the smooth operation of the vehicle
- Describe how brake chambers produce mechanical braking force
- Explain the importance of brake adjustment
