## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED INTO CLT DUE TO THE FLIGHT CREW REPORTING A BRAKES RIGHT RELEASED ECAM DISPLAYED DURING LANDING GEAR EXTENSION. THE FLIGHT CREW ABORTED THE APPROACH AND DETERMINED THERE WAS ONLY AN ISSUE ON ONE BRAKE CONTROLLER. THE AIRCRAFT LANDED SAFELY AT CLT WITHOUT FURTHER INCIDENT. MAINTENANCE REPLACED THE ALTERNATE BRAKE DRIVE VALVE AND ACCOMPLISHED A SATISFACTORY LEAK / OPERATIONAL CHECK PER AMM 32-43-35.
