Narrative:

Automatic brakes used on landing, more than regular deceleration experienced. After 23 mins taxi and holding time, ground controller informed us of left wing brake smoke and fire. Engines shut down and emergency crew arrived. After smoke was out, requested to be towed to the gate. Upon arriving to the gate and inspection, it was revealed no tire fuse melting. No tire deflation. No sign of fire or any other kind of damage, and no fire marks. I suspect we had residual grease in brake area and that was the reason for smoke and possible flash fire that caused another aircraft to report it to ground controller.

Narrative: AUTO BRAKES USED ON LNDG, MORE THAN REGULAR DECELERATION EXPERIENCED. AFTER 23 MINS TAXI AND HOLDING TIME, GND CTLR INFORMED US OF L WING BRAKE SMOKE AND FIRE. ENGS SHUT DOWN AND EMER CREW ARRIVED. AFTER SMOKE WAS OUT, REQUESTED TO BE TOWED TO THE GATE. UPON ARRIVING TO THE GATE AND INSPECTION, IT WAS REVEALED NO TIRE FUSE MELTING. NO TIRE DEFLATION. NO SIGN OF FIRE OR ANY OTHER KIND OF DAMAGE, AND NO FIRE MARKS. I SUSPECT WE HAD RESIDUAL GREASE IN BRAKE AREA AND THAT WAS THE REASON FOR SMOKE AND POSSIBLE FLASH FIRE THAT CAUSED ANOTHER ACFT TO RPT IT TO GND CTLR.
