it's essential to assess the ambient temperature.
When conditions are particularly warm outside, brake temperatures tend to heat up more rapidly and using maximum reverse thrust may help decrease them significantly. Under such circumstances, using maximum reverse thrust may also be beneficial in order to help lower temperatures during landing and reduce brake temperatures further.
However, in cooler environments you should switch to idle reverse thrust to reduce wear on the brakes and ensure they won't overheat by the time your plane lands or you reach its runway destination.
Considerations should be given when planning for turnaround times of 45 minutes to 1 hour, in which parking in shaded areas would prevent excessive heat build-up, with parking brake released until just prior to pushback for airflow around brakes and tires. Communicate your brake cooling concerns to the ground crew. They might be able to provide additional cooling measures like using water carts during turnarounds to spray cool water over your brakes for added cooling effects.
