If you notice a fault in the vehicle’s braking system on the airside, what steps should you take?

• A. Continue to operate and report after.
• B. Ignore fault if you can brake manually.
• C. Drive to a repair facility.
• D. Do not operate the vehicle, report the fault to supervisor, and secure the vehicle.

Answer: (D)

Not operating a vehicle when you notice a braking fault is about stopping risk before it starts. The safest step is to immediately report the fault to your supervisor and secure the vehicle so it cannot move. That way, no one else is put at risk and maintenance can inspect and repair the system before the vehicle is used again.

Continuing to operate and reporting later assumes the fault won’t worsen or cause a incident, which isn’t reliable. Ignoring the fault even if you think you can brake manually isn’t safe because a manual brake may not fully compensate for a hydraulic or pneumatic brake failure. Driving to a repair facility with a known brake fault could lead to a complete loss of braking at a critical moment. Securing the vehicle and stopping the operation now prevents movement and ensures the issue is addressed properly.
