Before adjusting a car’s brake bias or chasing a missed braking point, check what your foot is sending to the sim. A brake that registers input while you’re coasting or requires a different effort each lap is hard to learn around.
Set the ends of the range
Make sure the pedals and seat stay put under braking. Open the pedal manufacturer’s calibration tool, if it provides one, and follow the instructions for your model. The input should come back to zero when you release the pedal. If your hardware offers a lower dead zone, use just enough to eliminate any stray input. A large dead zone can hide the small applications you want to feel as you ease onto the brake.
A load cell brake measures force. If the manufacturer allows you to set the force for full input, choose a level you can reach repeatedly from your normal position without bracing on the wheel. A travel-based pedal calls for a different check. Follow its calibration prompts through the movement it uses to register the full range.
Check it in the sim
Run the sim’s own input calibration if it requires one. Watch its brake bar through a slow press, a full press, and a gradual release. Then try several laps at a familiar circuit and review where you reach peak input. If nearly every ordinary stop tops out at 100 percent, revisit your setting. If a firm press rarely reaches full input, check the range again before changing anything on the car.
Record the setting once you can reproduce it. Seat, pedal, and hardware changes are good reasons to run the same check again.
