## Discrepancy

LEFT SIDE BRAKES WOULD ENGAGE ON LANDING BUT THEN STOPPED WORKING FOR 1-2 SECONDS AROUND 60 KTS AND 15-20 KTS.  R & R BRAKE CONTROL VALVE. LEAK CHECKED GOOD BUT LH BRAKES STILL FAILED DURING TAXI CHECK. R&R BRAKE CONTROL UNIT WITH MODIFIED UNIT. LEAK CHECKED GOOD. OPS/TAXI CHECKS GOOD.
