What could excessive delays in braking indicate?

Excessive delays in braking can indicate possible air leaks or ineffective brake components because these issues directly affect the performance and response time of the braking system. In a properly functioning air brake system, the time taken to apply the brakes should be consistent and responsive to the operator’s input. If there are air leaks, it may take longer for the brake cylinders to receive sufficient air pressure to activate the brakes effectively. Similarly, ineffective brake components—such as worn-out brake shoes or faulty valves—can also lead to delayed response times. Monitoring for such delays is crucial, as they can signal potential safety hazards, requiring immediate inspection and maintenance to ensure the brakes are functioning correctly and reliably.
