we have temp gauges on some of the 737-300's ,and I was able to check the temp behaviour on short turn-around. I never saw it above 4,and the temp light should illuminate at 5,even when landing on short rwy's,with autobrake 3,max reverser will keep the temp in reasonable limits.
A long taxi will tend to raise the temp also,and using reverse idle will help keeping the temp down.
I've seen once smoke coming out from the brake assembly,and the temp was around 4,'hand ' test was ok. Some tech told me the brake's had just been changed..
Without temp gauges we use the tables ,and after landing on 1800m rwy's,20-25 min will be required for cooling the brakes on ground (reversers used at detent reverse thrust). In case one didn't use the reversers this time will go up to 45 min. (on the classics)
The NG (700) is a lot better _same conditions like above will give you no special procedure required on tables. Maybe that's one of the reasons we are using now mostly the NG's on short rwys.And we have one particular rwy (not only short,but also 30m wide) where the pax are always enjoying the 'carrier landings' .
So ,you see,with full reverse thrust there won't be any problem with the brakes.
Only problem we've ever had with the brakes was at a high speed RTO,followed by a long taxi to the apron resulting in fuse melt.
