Kit I am a professional pilot now but used to be a systems test engineer. Spent several months testing brake performance and can assure you that maximum manual braking IS variable. Whilst my involvement was not restricted to the A340 test I described it best illustrates the issue. They had four test pilots one of them did not apply max braking from the start (as it felt so severe)...non of the other three were able to maintain max braking until the stop. A combination of trying to keep the aircraft straight whilst apply full leg pressure and leg fatigue during the deceleration. The aircraft beat all four pilots (when it came to a stop tyres deflated). Maybe before you start patronising you should give others a little credit.BTW the pedals go nowhere near the stops when max foot pressure is applied.
BOAC think I used GLA 23 wet for the performance. As you say it is normally above max landing weight ...it is the overweight return case which raised this question. I would of course look at the QRH but the assumptions are different from the perf manual.
