Approaching number one position short of Runway 17L at Denver; my First Officer noticed the No. 3 Brake temperature much higher than the other three brakes temperatures; which were well in the 'GREEN.'I considered leaving the departure position; and allowing the brakes to cool from the outside airflow.I considered the airflow over the brakes if the landing gear retraction was delayed on departure.I finally considered the brake temp of the No. 3 brake to be erroneous; or at least untrustworthy; in comparison to the other brake temperatures.I consulted with my First Officer; and we concluded that the best course of action was to continue the departure; and use the departure airflow at altitude to ensure rapid cooling of the No. 3 brake. Our reasoning was the other brake temperatures were relatively cool for a takeoff; and the offending brake temperature was therefore likely erroneous as it approached max temperature for takeoff. The HOT BRAKE ECAM appeared just as we were entering departure position; and the No. 3 brake temperature was approximately 310 degrees. We continued the takeoff; left the gear down until 10;000 ft. and upon the No. 3 displaying 250 degrees; raised the gear and completed the flight uneventfully. If all four brakes had shown high temperature; or if the one hot brake displayed and extreme temperature; we would not have continued the takeoff.
A319 Captain reported an erroneous hot brake indication and elected to continue the takeoff.
