Operational Checks (Brake System)
Perform a visual inspection of the machine. Refer to Testing and Adjusting, "Visual Inspection".
When you diagnose a problem in the braking system, a visual inspection of the system is the first step. Before any tests are performed, visually inspect the entire braking system for oil leaks and for damaged parts.
Stop the engine and lower the implement to the ground. Engage the parking brake and perform the following inspections:
- Check the oil level in the sight gauge.
- Look for air in the oil that is in the hydraulic tank immediately after the engine is stopped. Use a clear container to obtain a sample of the oil. Look for air bubbles in the oil that is in the container.
- Check all oil lines and all connections for damage and for leaks.
- Inspect the braking system for damage.
- Start the engine.
- Release the parking brake and activate the service brakes while the machine is moving. Listen for any unusual noises. Ensure that the brakes stop the machine.
- Lower the implement and stop the engine.
