A B767 landed hard in a crosswind with autobrakes 3 selected and the right brakes stopped the aircraft creating high brake temperature while the left brakes remained cold. Ground crews applied a fire extinguisher to the right brakes at the gate.

Narrative:
Auto brakes [were] not used on first landing. On second leg switched runways. Weather was good visibility; light snow; wind 010/15g20 (direct cross). ILS seemed normal; autopilot clicked off around 500 ft. [We] got a sink in the flare that led to a firm touchdown followed by a slight bounce. Auto brakes were selected to 3 (short runway and snow) and the deceleration felt much more than auto brakes 3 normally. After clearing the runway and taxiing in; called up status page to start APU and noticed brake temps abnormal. Right truck had temperatures 7-7-5-6 starting top right and moving clockwise. Left truck had 0-0-0-0. No swerving on the runway and jet taxied normal. Very short taxi to gate and we called to tell ramp that we have possible hot brakes and would need to be chocked. I used only the left brake to taxi in and it worked normal. At the gate; we shut down and ran the parking checklist. We could see fire crews spraying our right truck in the glass reflection of the concourse. The co-pilot made a second call to ramp to have ground crews hook up and tell us when we were chocked and could release the parking brake. I made the final call to ramp reiterating we needed some one to tell us if we were chocked and could release the parking brake. We never saw any fire and finally released the brakes on the call by a maintenance supervisor who came into the cockpit. I never saw the right truck temps get above the 7-7-5-6. We input the maintenance write-ups until the ACARS timed out. I then called maintenance control and told them to add the brake temperatures to our write up and to write up a firm landing and slight bounce. I went out to inspect the right truck and was surprised that the tires had not deflated. I noticed no flat spots on the tires either. I have never seen brake temperatures above 5 and do not know how auto brakes could result in such an abnormal indication and unbalanced temperatures.
