It's actually a made up answer pulled straight from my butt.
A teeniest bit of a search would have revealed that it is in fact a star adjuster and the dimension is predicated upon the wear of the friction lining combined with the internal dimensional drum diameter. Properly adjusted, the star wheel adjuster spreads the shoes far enough apart at the bottom to keep the friction material in close enough proximity to the drum surface that a moderate application of the parking brake lever will create enough frictional resistance to stop the vehicle from rolling on mild to moderate inclines.
I figured since you like to make threads that turn into FUBARfests of phenomenal proportions, I'd get you started off on the right foot.
You were supposed to ask how one gets an accurate measurement.
