Prior to 9/11 I made an approach to Heathrow in the jump seat with a pilot I knew (still know, for that matter) in a 757. We landed with full autobrake, full reverse thrust, all the lift dumpers and anything else that would slow us (plane following us was reported as too close). As we pulled off 27R the brake overheat warning went off. I was a bit surprised when the co-pilot went delving into the manual as we taxied but the answer he came up with was that they would have to tell the next crew to wait a bit longer than the planned turnaround (I seem to remember the extra was 40 minutes but I have no idea what the planned turn time was).
I know the 757 and 767 have different weights etc but I'm a little surprised that one would need cooling by the fire service and the other wouldn't.
