You're thinking of it the wrong way around. The higher the value the harder you have to press it to get the same amount of braking - go ingame and try it. Setting it to 0 is only for load cell pedals, any others you'll need to turn it up in order to get more realistic braking. Even iRacing said that's the way round it works.

Controls

Brake calibration has been updated to work well with both pressure-sensitive and deflection-sensitive brakes. There is now an option to control the linearity of the simulator’s brake pressure response to your physical brake pedal travel. Potentiometer-based pedals (most pedals) can adjust this value to suit what feels best for them; lower values give a more linear brake response (more initial brake force with pedal travel than before), while higher values give a more non-linear increase in brake force (less initial brake force, more force near full pedal travel). Linear pressure sensitive pedals (with load cells) should set this value to zero for the most linear true to life feel. A brake force curve factor of 2.0 is close to the brake force curve before this change. This factor is now reset automatically to 1.8 any time the brakes are calibrated—you will need to change it to your preferred value after calibrating the brakes if 1.8 is not to your liking. For most pedals this gives a good feel.

The pedal meters on all screens reflect this change. The throttle meter has also been corrected to match on all screens.

I have to re-calibrate my brake pedal with iRacing every time i launch it, gets a bit tedious after a while

You can calibrate and save for each different car. Did you know that?

sounds good aritan, that car is a hard car to drive hahha

 

[Aritan Maia]

You are gonna get the hang of it sooner than you imagine... And when you do, awesome races to come!!!!

ok mate sounds nice

No. Please read what I wrote. With a value bigger than 0 the brake gets more and more unlinear and progressive. That moves the braking point later but at the cost of precision. If you are using a high value and then switch to 0 you need to press the brake less as the brake curve is different - the point at which you are on threshold braking comes sooner with 0 value. But you have a much bigger window which means better consistancy and better precision.

Setting it to 0 makes the pedal linear which is best for travel sensitive brake pedals. That's how it is in other sims. With travel sensitive pedal that is also closer to reality than some unlinear curve. Real car's brake pedal is linear to pressure. Te harder you press the pedal the harder the brakes slow the car down. Of course there is some movement in the beginning but closer to the limit of threshold there isn't.

What iracing says, or said is only part of the truth. Their idea behind the unlinearity is (I think) to try to mimic the travel sensitiveness of the real brake pedal. Which isn't really travel sensitive at all - it's pressure sensitive. But when you look at the travel sensitiveness of the real brake pedal it looks like a a very unlinear travel sensitive brake pedal. If you plot a curve between brake-% and braking effort on the wheels you probably get a curve that is unlinear and looks like a curve of x^2. It gets "steeper" towards the end. But it is wrong and unrealistic because the travel sensitiveness is not the important part of the characteristics of the real brake pedal. The pressure sensitiveness is and that is not unlinear.

He talks about feel, not realism.
