About 2 hours after departure; en route; we received an EICAS message: C HYD LO QTY. Pulling up the Status page showed the quantity at .49 and decreasing. We performed the proper QRH checklist and then Maintenance and Dispatch were advised. We planned on a flap 20 landing at our filed destination with Alt flap extension using a long final and continued. When we checked in with Center nearest our destination an emergency was declared. During the Alt flap extension we got a LE Disagree EICAS and ran that checklist. When attempting to extend beyond flap 5 we also got a TE Disagree EICAS and ran that checklist as well as calling Maintenance to see if they could help in case we overlooked anything and to get more flaps out. All efforts to get more flaps out were unsuccessful. After recalculating a new landing weight and landing distance for a flap 5 landing we decided a safe landing could be accomplished. With the Captain flying; the approach; landing and rollout were uneventful. Using Alt nose wheel steering we were able to proceed to the gate unassisted.
A B767 EICAS alerted C HYD QTY in cruise so on approach to the filed destination the crew declared an emergency and while extending the flaps received EICAS TE DISAGREE and LE DISAGREE alerts which required additional QRH checklists before landing.
