Before performing a brake test, the air hoses must be in what condition?

• A. In serviceable condition and properly coupled.
• B. Exactly two feet long.
• C. Color-coded by car type.
• D. Wrapped in protective cloth.

Answer: (A)

Before performing a brake test, the air hoses must be in serviceable condition and properly coupled. Serviceable means the hoses are free from cracks, leaks, wear, or damage and can hold air pressure without losing it. Properly coupled means the hose ends are fully connected and locked so the connection is tight and leak-free between the test equipment and the train’s air system. If hoses are damaged or leaking, the test readings won’t be accurate and there’s a safety risk from unexpected pressure loss. If the hoses aren’t securely connected, they can detach or leak under pressure, compromising the test and potentially causing an unintended brake action. The other ideas—fixed length, color-coding, or wrapping in cloth—don’t impact the essential safety and reliability of the pre-test connection.
