Can't play with the T3PA Pro

Hi guys, I'm trying to play this awesome game, but somehow it recognizes throttle and brake as a single axis. I tried to combine them in the Thrustmaster control panel, but I only get the throttle to work, there is no sign of brakes. I also tried using vJoy and Universal Joystick Remapper to get a virtual joystick with 2 axis. The game recognized throttle and brake as different axis under controller B (while the wheel is A) but when going on track nothing happens, it's like there's no input.
How can I get it to work?
