Hi,I had the strangest Autobrake problem the other day.I was flying out of EFHK, and started the t/o roll normally. At 100kts the wheel brakes suddenly went to maximum braking. I first thought that I had an engine failure, and the RTO mode had gone off in the autobrake system. Nope. I taxiied back into position, and verified all systems were go, and set Autobrake again to RTO. Off I went, at 100kts boom... brakes. Again maximum braking, and I'm puzzled. Well, I taxied back to the gate, and scraped my head for a while. I could NOT locate anything wrong with the aircraft. I even used the "PIC repair all failures" -option in the PIC menu. Nothing was broken, according to it. Well, as I have IRL B767 AOMs, MMEL plus a few other things, I grabbed the MMEL and checked for the Autobrake system. Great! I don't need the darn autobraking to fly, so I switched off the Autobrake system. Then taxied back into position, and tried again. Well, waddaya know... the brakes didn't go off this time, and I happily lifted off towards EFKK!I had some anomaly in the Autobraking system... nothing that I could pinpoint. But disabling the Autobrakes solved the problem. :) almost like real-life ops, heheeregards,Tero

now i come across this problem whenever i use the N1 button and do leave the throttle on the stick at the idle position.in case you are doing something similar, just increase throttles as soon as you press the N1 button and it will maintain the "throttle hold" without cutting the power at 100kt.
