## Discrepancy

CAPTAIN REPORTED THAT AFTER LANDING ROLL THE AIRCRAFT WAS UNABLE TO MOVE BEING NECESSARY TO ADD THRUST, HEARING A STRONG NOISE.  AT PLATFORM, MAINTENANCE PERSONNEL DETECTED THE MLG WHEEL AND BRAKE ASSY POSITION 2 DAMAGED, SO THEY WERE REPLACED IAW AMM 32-45-11 AND 32-41-4.  LATER, DURING ANTISKID/AUTO BRAKE TEST IAW FIM 32-42 TASK 801, THE PWR A/B FAILURE MESSAGE WAS SHOWN, SO THE FAILURE WAS DEFERRED IAW MEL 32-7-1 CAT "C" AND THE AIRCRAFT WAS DISPATCHED.  DURING OVERNIGHT CHECK AT MEX, THE SERVO VALVE PRESSURE SWITCH WAS REPLACED AND TESTED IAW MM 32-42-81 AND FIM 32-42 TASK 801, ALL CORRECT AND THE DEFERRED REPORT WAS CLOSED.
