Repair or replace it before proceeding

If you notice a leak in your service line during a pre-trip inspection, the appropriate action is to repair or replace it before proceeding. This is crucial for ensuring the safety and reliability of the vehicle while on the road. A leak in the service line can lead to a reduction in the effectiveness of the air brake system, which could compromise your ability to stop the vehicle safely. Addressing the issue promptly by conducting repairs or replacing the line not only adheres to safety regulations but also prevents potential failures that could lead to accidents or further mechanical issues during operation. Prioritizing vehicle integrity is essential for both the driver’s safety and compliance with transportation regulations.
