Narrative: On final approach at approximately 500 feet; the Relief Pilot called out 'left hydraulic quantity EICAS.' Moments later; he stated; 'you've got multiple failures happening.' I directed the First Officer (FO) Pilot Flying (PF) to continue flying and to continue the approach. The Relief Pilot reached for the checklist and stated that we probably will not have nose wheel steering. I called the Tower and told them that we lost our left hydraulic system and will be stopping straight ahead on the runway; then continued my duties as the pilot not flying. On short final; we noticed the flaps had stopped at flaps 25 instead of planned flaps 30; therefore we adjusted our approach for flaps 25. Although a little gusty; with a 5+ knot crosswind; our landing was normal. After manually extended the speed brakes; I took control of the aircraft. I attempted to use the nose wheel steering and found it was indeed inoperative. As the aircraft slowed; I realized I had enough directional control ability through differential braking that we could clear the runway via a high speed taxiway. After clearing the runway; I brought the aircraft to a stop and set the parking brake. Emergency vehicles reported that we continued to leak hydraulic fluid; therefore we shut down the engines and turned off all hydraulic pumps.


Second narrative: During the final approach to Runway XXL in ZZZ I asked for flaps 20; gear down. Right after the gear came down we got an L HYP QTY EICAS message. We continue the approach since there was not time enough to complete the QRH; I called for flaps 25 and we received several other EICAS messages (L HYD SYS PRESS; TE FLAP DISAGREE; L YAW DAMPER; SPOILERS; and RUDDER RATIO) We quickly reviewed the things that probably may be lost like nose wheel steering; and adjusted the speed for a flaps 25 landing. The approach was continued and we let Tower know that we were having a hydraulic problem. I had to use full aileron deflection at times to maintain control of the aircraft. Once we landed we were able to exit the runway and the emergency vehicles came very quick. We were immediately notified that fluid was pouring out from the bottom of the aircraft. After a while we were towed to [the] gate with no further incident.


Synopsis: B757 flight crew reported hydraulic system anomaly on final approach; resulting in several configuration and braking adjustments.
