## Discrepancy

CREW REPORTED THAT UPON LANDING, THERE WAS NO BRAKING FROM EITHER THE CAPTAIN'S OR FIRST OFFICER'S BRAKE PEDALS.  THE AIRCRAFT WAS SLOWED WITH USE OF THE THRUST REVERSERS AND AT APPROXIMATELY 10 KNOTS, THE BRAKES BECAME EFFECTIVE.  MAINTENANCE REPLACED THE BRAKE CONDITIONING UNIT DUE TO CMC MESSAGING AND RESULTS OF BRAKE ANALYZER SOFTWARE THAT WAS UTILIZED.  OPERATIONAL CHECKS AND TAXI CHECKS OF THE BRAKING SYSTEM WERE SUCCESSFUL WITH NO FURTHER DEFECTS NOTED.
