What should drivers do if they notice a significant air leak in the braking system?

When a driver notices a significant air leak in the braking system, immediately pulling over and assessing the situation is crucial. Air brakes rely on a specific level of air pressure to function safely, and a significant leak can compromise the effectiveness of the braking system, leading to a potentially dangerous situation while driving.

By stopping the vehicle right away, the driver can prevent further risk of brake failure, which could lead to accidents or loss of vehicle control. This immediate action allows the driver to evaluate the severity of the leak and determine the next steps, whether that's contacting maintenance for repairs or performing basic troubleshooting if trained to do so. Ignoring the issue or delaying action could escalate the problem and put the driver, passengers, and others on the road at risk.
