A B767-300 flight crew reported they experienced smoke from a hot brake after landing; even though normal braking was used. CFR responded; and after cooling; the flight proceeded to the gate.

Narrative

We landed with a gross weight of approximately 274.0. The landing was normal with normal braking. As we turned onto [the] taxiway; the [aircraft] that we were to follow reported some smoke coming form our left main landing gear. All brake temperatures were low with all indicating 1 or 2 readings except Right Main Forward Inboard on 3 with a white box. Tower confirmed the smoke and declared an emergency so I stopped while we waited for Crash Fire Rescue equipment. I had already shut down the right engine and I was able to keep the airplane stationary without setting the parking brake by turning the nose wheel to the left and monitoring closely. I advised the passengers that equipment would approach the airplane and asked them to stay seated. Crash Fire Rescue arrived quickly and I briefed them on the alternate Ground Control frequency. The Crash Fire Rescue team inspected our brake and indicated that the smoke had stopped and their heat gun indicated the highest temperature on any brake was 300; consistent with our EICAS indication. By now; about 15 minutes after stopping; all brake temp indications were 1 or 0. After conferring with the First Officers; Dispatch and Maintenance; we all agreed that it would be safe to continue taxiing the short distance to [the] gate with Crash Fire Rescue monitoring. We taxied uneventfully to the gate; Crash Fire Rescue indicated that all still appeared normal and we canceled the emergency.
