## Discrepancy

THE FLIGHT CREW REPORTED UPON POST FLIGHT INSPECTION, NOTICED POOL OF HYDRAULIC FLUID ON GROUND NEAR LEFT MAIN BRAKE, AND FLUID ON BRAKE LINES DRIPPING. THE MAINTENANCE TEAM DISCOVERED THAT THE LEFT BRAKE SHUTTLE VALVE WAS LEAKING. THE VALVE WAS REMOVED AND RESEALED WITH NEW ORINGS. THE VALVE WAS REINSTALLED AND THE SYSTEM BLED. OPS AND LEAK CHECKS SATISFACTORY.
