What should be done if an emergency vehicle's brakes feel spongy during operation?

When an emergency vehicle's brakes feel spongy during operation, it indicates a potential problem with the braking system, such as air in the brake lines or a failing brake component. Choosing to notify a supervisor and take the apparatus out of service is the correct action to ensure safety. This response allows for the vehicle to be evaluated by a qualified technician who can properly diagnose and fix the issue.

By removing the vehicle from service, you prevent the risk of brake failure while responding to emergencies, which could compromise the safety of the operator, passengers, and the public. It’s crucial to prioritize safety and reliability in emergency vehicles, and addressing any irregularities in braking performance is essential to maintaining that safety.

Utilizing options that involve continuing to operate the vehicle or adjusting driving style without addressing the underlying brake issue can lead to dangerous situations. Similarly, using the emergency handbrake to stop should be reserved for extreme situations, as it can lead to loss of control if engaged incorrectly or while in motion. Therefore, immediately reporting the issue and taking the vehicle out of service is the best practice in this scenario.
