What should be done if there are signs of leaks in the air brake system?

When there are signs of leaks in the air brake system, it is crucial to immediately repair the leaks. This is because any leakage can significantly impair the braking efficiency and performance of the vehicle, leading to potentially dangerous situations while driving. Air brakes rely on a pressurized system to function correctly, and a leak can compromise the system's ability to create enough force to engage the brakes effectively.

Prompt repair not only ensures the safety of the vehicle operator and other road users but also helps maintain the integrity of the braking system. Taking immediate action prevents the issue from escalating, which could lead to more extensive and costly repairs down the line.

The alternative choices lack a proactive approach to safety and maintenance. Ignoring the issue or only documenting it for future reference could lead to catastrophic failure while on the road. Additionally, performing unrelated checks does not address the critical issue at hand and may divert attention from necessary repairs that should be prioritized.
