Hi!,
The ideal temperature for brake usage depends on the type of brakes your company has but as a general rule brakes work best above 80 to 100 C..
The reason for the brakes hot warning at 300C in the A320 is to prevent the brakes from getting hot enough in the wheel bay to ignite any leaking hydraulic fluid and cause a fire in the wheel bay.
Also, there is an issue with the brakes over 300C giving rated performance in case of a rejected T/O.
Remember fuel saving is ok but if you go out of the runway only you & your license will be held responsible.....
