Think Formula 1 racing. Cold brakes don't work. HOt brakes do, except the formula 1 guys have the energy absorption rates available. We do not, hence the cooling tables.

I said it before, and here it is again, if you do the recommended technique of TK you will consistently have much hotter brakes than manually braking, the qualifier is that runway length is not an issue. If you want cooler brakes or have a quick turn, such as OGG, DO NOT USE AUTO BRAKES! If you're not worried about the temps, go ahead and use auto brakes.

I would never ever use 25 flaps on the 767-300, unless you need it for the gust factor. That tail is just too close to the ground during the flare.

767-300's all have carbon brakes, 757-200 Pratt's all have steel brakes, with the noted nose numbers 02-12 having very touchy brakes.
