## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED ON APPROACH INTO CLT. THE FLIGHT CREW REPORTED THAT ON GEAR EXTENSION THEY RECEIVED AN ALTERNATE BRAKE FAULT, AND THE FLIGHT CREW WENT AROUND AND ON THE SECOND LANDING ATTEMPT THEY RECEIVED THE SAME MESSAGE FOR A SYSTEM 1 FAULT. THE AIRCRAFT LANDED SAFELY AT CLT. MAINTENANCE REPLACED THE RIGHT-HAND ALTERNATE BRAKE MANIFOLD ASSEMBLY AND ACCOMPLISHED A SATISFACTORY LEAK / OPERATIONAL CHECK.
