## Discrepancy

ON TAKEOFF ROLL AT ABOUT 60KTS ECAM ALERT OF GREEN  HYDRAULIC SYSTEM LOW PRESSURE. WE GOT TWO ECAM  WARNINGS, ONE RIGHT AFTER THE OTHER. RTO, AUTO  BRAKES DID NOT ENGAGE BEC OF LOW SPEED.  TSM 29-32-00 FIG 105  AMM 29-14-00-03 JRH CH5 WITH REF ABOVE RAN NR 1 AND 2 ENGINES.   SYSTEM PRESSURE WAS NORMAL. GREEN HYDRAULIC SYSTEM QUANTITY WAS ABOVE TOP HAT. CYCLED ALL FLT CONTROLS MULTIPLE TIMES & SYSTEM BLED DOWN TO THE VERY BOTTOM OF THE TOP HAT. VERIFIED THAT THE RESERVOIR HEAD PRESSURE AND ACCUMULATOR PRESSURES WERE WITHIN LIMITS. NEXT STEP PER TSM 29-32-00 FIG 105. TO CHANGE HP MANIFOLD PRESSURE-SWITCH (30WW) AMM 31-53-51-04 AMM 12-12-29-00 TSM 29-32-00 FIG 105 JRH CH 5 WITH REFS ABOVE. REMOVED AND REPLACED GREEN SYS HP MANIFOLD PRESSURE-SWITCH (30WW). OPS & LEAK CHKD GOOD. RAN NR 1 AND 2 ENGINES AGAIN AND CYCLED  FLIGHT CONTROLS MULTIPLE TIMES. HYDRAULIC QTY STAYED AT THE BOTTOM OF TOP HAT. NO FAULTS NOTED. SERVICED GREEN SYSTEM HYD   FLUID TO MIDDLE OF TOP  HAT. ACFT OK TO CONTINUE.
