How to set deadzone for my wheel?

Hi! all. I have logitech momo racing wheel. But my brake pedal have problem: it's always increase about 20% although my leg don't push on it. So i want set my deadzone in gp4 for my brake pedal about 30%. Please guide me how to do this!

I'm not sure deadzones can be set in GP4, only a low sensitivity zone (though I'm not sure exactly how that works). Have you tried recalibrating the wheel in the contoller setup menu though?

you cant setup a deadzone in gp4!

i have a logitech driving force pro and i have the same problem with the throttle.

you must open the pedals and clean up this!
