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

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

Answer: (D)

Leaks in brake lines and fittings indicate a compromised hydraulic brake system and must be identified during inspection. Brake lines carry pressurized fluid; any seepage or wetness around the lines or at fittings means the system cannot maintain proper pressure, which directly reduces braking effectiveness and can lead to complete loss of braking. While corrosion, cracks, or loose connections can contribute to leaks, the observable sign you’re looking for is fluid leakage itself. During the check, look for damp spots, staining, puddles, and listen for any hissing sounds from fluid escaping; if leaks are found, address the source and restore proper fluid levels and integrity before operation.
