I am having a big problem with wilco a380. I selected the auto brake before final approach. After touching down, auto-brakes work properly. But when the nose wheel touches the ground, auto-brakes just disarm automatically, and I can't reengage it on the ground. This is quite inconvenient for a landing. I have tried to put default auto-brake gauge of 737-800 into wilco a380, but the problem is still there. However, auto-brake works perfectly in my default 737. Anybody have any idea to solve this problem, or anyone have a utility to replace the auto-brakes? I am using FSX+Acceleration. Thanks for your help.

After a few hours of work, the problem was finally resolved.This problem is caused by error contact points data in aircraft.cfg. FSX considers the main wheel is NOT fully contacted with the ground so auto-breaks would not be automatically deployed.I fixed the problem by merging with project airbus A380, changing contact points data based on pa's aircraft.cfg.
