@RHill: I've tried to explain it in the documentation:
The braking range is normally read from the magic data, so it's track specific but affects all cars. The values in the magic data are better known as desc51 and desc52, or CC aggressiveness. I noticed that desc51 works like a minimum value and desc52 as a maximum value, and that the cars will brake for a corner somewhere in this range (relative to the normal braking point), so that's what I've called it. A negative value will make them brake earlier, and a positive value will make them brake later. Usually desc51 will be negative and desc52 positive. Note that if you edit the magic data, negative values will be between 32768 (equals -32768) and 65535 (equals -1). Note that if the car's grip value is increased, the braking point is increased (moved ahead) too. The braking range values are added on top of this.
With GPxSet it's possible to have a braking range individually for each car. It can be specified in the performance text file under section [BrakingRangeMin] and [BrakingRangeMax]. The key names are Team #00 through Team #10. Each value consists of two comma separated numbers, one for each car, though if one value is used, it will affect both cars of that team. The BrakingRangeMin and BrakingRangeMax values work the same as desc51 and desc52 in the magic data, and do not replace them. Rather, they are added to the corresponding magic data value for a specific car. The formula is not exact, but to get an idea, it looks like: braking range value = grip + magic data value + car specific value. If the value becomes too high, it's likely the car will overshoot a corner, especially slow corners. If the values becomes too low, it's likely the car will brake early even for fast corners ahead and becomes a danger to other cars, though very easy to outbrake.
It's possible to exclude this patch even when the values are present in the performance file. This can be done in gpxset.ini, section [PerfManager], key PatchBrakingRange. Use value 0 to disable it. The default value is 1.
