I have tested the demo with both of my wheels, and the brake is super sensitive. I have the deadzones set to 0/100, and I am getting 70+ braking from barely any pressure on the pedal itself. The game really needs a “linearity” adjuster for the brake pedal. Preferably with the default at 50% (just like the steering), leaving the player with plenty of room to adjust for personal preference.
Funny, on Xbox One I have the opposite problem. My G920 can’t get the brakes any higher than about 75%, even with the deadzones set to 0-20
