Which statement best describes the function of the independent brake leakage test result if leakage is found greater than 5 psi?

Which statement best describes the function of the independent brake leakage test result if leakage is found greater than 5 psi?

• A. Check for leaks and retest
• B. Proceed with CW
• C. Ignore the result
• D. Reduce train speed

Answer: (A)

When the independent brake leakage test shows more than 5 psi, the key idea is that the brake system is not holding pressure properly and a fault exists that must be addressed before moving. The correct action is to locate the source of the leak, repair it, and retest to confirm the system now holds within the allowed limit. This ensures the independent brake will function reliably when needed. Proceeding with movement or operations after a leak above the limit is unsafe, and ignoring the result or simply reducing speed does not fix the actual leak or confirm brake reliability.
