Hello

I downloaded the script and tried to play around a little with in order to get a better view of how we should set up our brake system in or FS car. However, while comparing to other sources something with the script does not add up.

According to what I can find the tire friction lines (uxf and uxr) should coincide at the optimal distribution curve and the constant acceleration line. So, for example the lines from uxf = uxr = 0.7 should coincide where the line for 0.7g's of brake acceleration would be. Also this should be right where the ideal braking curve is.

I tried setting the air density to 0 in order to zero out any speed-related terms, only considering "pure braking" without any aero-effects. The ideal brake curve is perfectly in line with my hand computations but the constant friction lines do not behave according to the theory. I am no matlab expert, but I tried checking your formulas for the constant friction lines and compared them to different other sources and they seem to be fine. Additionally, I have verified that for the uxf lines the point of intersection with the Y-axis has the correct value. That leaves me believing that somehow, the slope of the lines is incorrect although the math behind them seems to be okay.

Have you run into this issue and what is your opinion on it? Is there a way I can try to look at it myself? Any help or suggestion is very much appreciated!

Best,
Jonatan
