That air of the brakes should be very hot and is almost independent of surface characteristics.
Slamming on the brakes on the parade lap or anytime during the race is sure enough to generate enough heat to warm the rims and then the tyres, regardless of the track conditions.
I suppose they may have an interesting ducting arangement to circulate some of that hot air before it exits the wheel rim.
Possibly Red Bull isnt the only one doing so. Where pre-pirelli times teams ran fully enclosed brake setups, now there are holes, or even fully exposed brake discs.
