As a side note, it would be nice if rFactor 2 had some telemetry data regarding this. Right now, there's no way to tell how much brake disc is left. How to tune the brakes First of all, you need to find out what is the brake response curve of the mod you are racing. In the HDV file ([url=index.php?option=com_content&view=article&id=12:extracting-the-physics-files-out-of-an-rfactor-2-mod&catid=18:tips&Itemid=283]read this article on extracting the physics files out of a mod[/url]), look for: BrakeResponseCurve= Example: BrakeResponseCurve=(195,450,715,1610) Each wheel has its own BrakeResponseCurve, usually, front and rear are the same, but it is worth mentioning this.
[b]Meaning[/b]First 195 Indicates the brake temperature at which braking torque is half the optimum. Second 450 Indicates the minimum brake temperature for optimal braking torque. Third 715 Indicates the maximum brake temperature for optimal braking torque. Last 1610 Indicates overheated temperature at which braking torque is half the optimum. Now you know that your optimum braking temperature is found between 450 and 715 degrees Celsius. Using a data analysis software, like Motec, you would check the brake temperature values, what you should keep an eye on is what is the temperature at the initial application of the brake. You would want this to be close to 450 degrees, anything far under that value and the braking torque will not be optimal. Then with the braking pressure, you would tune up the brakes so that the peak doesn't go too above the maximum optimal temperature of 715 degrees. It is okay if you go above the optimal, just make sure it is not for a long period of time while the brakes are pressed, you would be losing braking torque if that's the case. You should also configure alerts in Motec to notify you if the brake temperature has gone beyond 1610, which will certainly destroy them quickly. You should also tune in the brake BIAS so that the average temperature for the front brakes are almost the same to the ones on the rear, do this and you will have an even distribution where all brakes will fade out more or less the same amount during a race.
