## Discrepancy

REPEAT WRITE UP INITIAL BRAKE CHECK ON F/O SIDE UPON LEAVING CHOCKS IS SATISFACTORY. HOWEVER, AFTER FLIGHT THE F/O BRAKES ARE COMPLETELY INEFFECTIVE (BOTH SOFT PEDALS F/O SIDE) FOR THE LAST 2-3 SECONDS (CONTINUED FROM ABOVE) AFTER INITIAL BRAKE APPLICATION. AFTER THIS PERIOD, NORMAL BRAKING IS AVAILABLE TO THE RAMP.  CAPT SIDE BRAKING SEEMS NORMAL AT ALL TIMES.  REPAIRED SHIELDING TO LT WHEEL SPEED TRANSDUCER. REMOVED AND REPLACED RELAY KN002. ALL WORK DONE IAW WDM CH 32-40-01. GROUND CHECKS GOOD. PERFORMED ANTI-SKID WIRING CHECK AND FOUND SHIELDING FOR LT WHEEL SPEED TRANSDUCER HARNESS WAS NOT CORRECTLY GROUNDED, REPAIRED DEFECTIVE WIRING IAW WM 32-40-01.
