Aircraft
We began our descent and received a Master Warning Caution light with a 'TE FLAP ASYM' EICAS message. We had not changed our configuration prior to the illumination of the lights. There was no rolling moment of the aircraft or any other aircraft control problems. We went through the QRH and felt we needed more time to work our checklists so we asked the Approach Controller if we could hold. We received clearance to hold at 7;000 FT. During the hold; we contacted [Operations and Maintenance] to inform them of our situation and [Maintenance] felt there was nothing we could do airborne to fix the problem. We worked through the checklist ensuring all steps were adhered to; including calculation of our approach speed given flaps were between up and 1 degree. We then declared an emergency with Approach Control; asked for a 10 mile straight and began our approach. Upon switching to Tower; we asked to stop on the runway and wait for the fire trucks to inspect our brakes prior to taxiing. We touched down on target airspeed and rolled to a stop with approximately 5;000 FT remaining. We switched frequencies to match the Fire Captain who informed us that the brakes did not register excessive temperatures. We switched back to Tower and asked to taxi to the ramp.
