Yesterday I experienced an aborted takeoff at Kochi, Japan in ANA 767-300. Briefly, a sudden decelleration and silencing of the engines, followed by a short burst of reverse thrust. The pilot had seen a flock of birds on the runway. [The flock must have then been scared away because a JAS Airbus A300 landed right behind us] We had to wait at the terminal "for the brakes to cool down" for about 20 minutes. I suppose this was to ensure good braking efficiency for the next attempt. We took off again and the flight proceeded uneventfully to Haneda until on taxiing, I heard loud moaning and felt heavy shudders whenever we were braking. Questions 1: what exactly needs to cool down after such a heavy brake application? Is it the hydraulic fluid or the brake discs and pads themselves? I dont understand why hot brake surfaces should work less effectively than cold ones, unless they melt or something 2: Given the shuddering and groaning of the brakes, what would need to be done to them in the way of repairs?
