Perhaps a bit of thread creep here, but in the last couple of years have flown my first aircraft with brake temperature indicators (767-300 – understand it’s an option, not standard equip.). I have noticed no difference between front and back axle temperatures. What I have noticed, and it came as a bit of a surprise, is the large difference in brake temperatures on upwind/downwind trucks landing in a crosswind. There are consistently higher temperatures on the downwind truck when landing in a crosswind. Seems myself and every other pilot I have flown with are using a bit more brake than we realized in conjunction with the rudder to keep the aircraft tracking straight after touchdown.
