## Discrepancy

AIRCRAFT WAS GROUNDED: #2 WHEEL BRAKE LOCKED UP ON TAKEOFF ROLL. FLIGHT CREW REJECTED TAKEOFF AT 100 KNOTS. FLIGHT CREW REPORTED THAT THE #2 BRAKE WAS AT 305 C AT INITIAL BRAKE OVERHEAT ECAM MESSAGE AND MAX BRAKES WERE INITIATED BRIEFLY DURING THE REJECTED TAKEOFF BUT KICKED OFF IMMEDIATELY. #2 BRAKE TEMP EXCEEDED 900 C AFTER CLEARING THE RUNWAY AND BOTH TIRES ON THE #1 MAIN GEAR WENT FLAT. THE AIRCRAFT WAS TOWED TO HANGER AND DEPLANED. MAINTENANCE REPLACED THE #2 BRAKE ASSEMBLY (AALA202409109961) AND REPLACED THE LEFT MAIN LANDING GEAR NORMAL BREAKING SAFETY VALVE 2616GM (AALA202409104765). A SATISFACTORY OPERATIONAL CHECK WAS ACCOMPLISHED.
