Your problem is that when you release the parking brake, your normal brakes remain engaged? This has nothing to do with altitude. I would guess that you have pedals and they need to be re-calibrated.

Good Evening Paul,Whe i release parking brake the normal brake remain engaged and i on my keyboard continue press the dot for release... brake not desactivated, i have only joystick hotas, and never use pedals hardware, the brakes afected for high altitude?Thanks for your reply...Best RegardsCristiano

Normal brakes are applied only on demand. If FSX is telling you they are on, it is because something is telling FSX to put them on. If you aren't using pedals, then check if the trigger on your HOTAS is sticking.
