During a monthly MRES inspection, brake lines and fittings should be inspected for?

• A. Cracks
• B. Leaks
• C. Corrosion
• D. Loose connections

Answer: (B)

When inspecting brake lines and fittings, the most important thing to check is for any leaks. A leak shows that hydraulic fluid is escaping under pressure, which directly compromises braking performance and safety. Leaks can indicate damaged lines, degraded fittings, or loose connections, and they may appear as wet spots, stains, or damp areas around joints and along the lines. Detecting leaks helps ensure the system remains properly pressurized and capable of delivering the required braking force. Cracks, corrosion, and loose connections are serious issues as well, but they typically present risk through their potential to cause or accompany leaks. The presence of a leak is the clearest, most immediate sign that the braking system is not functioning safely.
