Narrative:
Slowing from 210 KTS to 180 KTS; we selected flaps 5 degrees. We then got a flap asymmetry EICAS caution. We stayed at 6000 ft and did a large square pattern while running the QRH checklist. We realized that no further movement of flaps were possible; so set up for a full slats/no flap landing. We declared an emergency and rolled the equipment to make sure the brakes were not compromised during a high speed touchdown landing. The first officer flew a constant rate of descent approach to touchdown with autobrakes 4. Crash fire rescue equipment reported no problems with the brakes and we taxied to the gate. Except for the high speed approach and landing; no other problems were encountered.

WE DECLARED AN EMER AND ROLLED THE EQUIP TO MAKE SURE THE BRAKES WERE NOT COMPROMISED DURING A HIGH SPD TOUCHDOWN LNDG. THE FO FLEW A CONSTANT RATE OF DSCNT APCH TO TOUCHDOWN WITH AUTOBRAKES 4. CFR RPTED NO PROBS WITH THE BRAKES AND WE TAXIED TO THE GATE. EXCEPT FOR THE HIGH SPD APCH AND LNDG; NO OTHER PROBS WERE ENCOUNTERED.
