Problem with gamepad

Hello everyone! I have such a problem: when I press LT (left trigger (brake)), then when I press the sticks (turn, turn the camera) LT is canceled. I cannot, for example, press the brake and turn it at the same time, or else I cannot take it back and turn the camera. I use a cheap Chinese gamepad (for $ 1 (yes for $ 1)). In other games I do not observe a similar problem. Maybe someone knows the solution to the problem? P.S. im sorry for my bad english

Buy cheap stuff expect poor results

I know but i have problems only with fh4 and emulator showing that gamepad working fine. Thats why im asking.
