Are you loading from a saved situation? Try loading a clean free flight, and before you do, ensure you choose a different model NGX than you want to fly (like the 900 if you're using the 800) then switch back to the 800 and then load up the flight. See if your brakes come on then. No matter what I did, I couldn't resolve the problem until doing that. FYI, the manual states the NGX doesn't like to be reloaded and the documented cure is to load a different model then load back the aircraft you want. I'd suggest doing this before every time you fly to ensure the aircraft is properly initialized (before it's initialized at the start of the flight, lol).

I had an issue with the original RTM with not getting any brakes...only happened twice. I chalked it up to FSX confusion with the PMDG "chocks" causing some confusion with the FSX parking brake command - like they were working opposite to each other. Uninstalled and reinstalled the livery and things seemed to fix themselves. Haven't had a problem since Hotfix 3.

thks mates, im try that.
