Most of the time, UAL is incapable of turning the plane in the time it would be required to wait for the brakes to cool, so it doesn't really matter. The only thing is, if the brake temp light is on, 5 or higher, now you need to make a write up and MX gets involved to make sure you don't blow a fuse plug.

Like I said, most of the time, not an issue, except on short runways, OGG, LIH.

It's a balancing act, higher temps and less wear vs. running off the end of the runway, more wear with cool brakes... carbon brakes are counter intuitive.
