I agree, I would THINK the arm couldn't change the reading (the line on the splined shaft). With the brake depressed, it of course moves further down on the range marking, but still doesn't even hit halfway in the middle.

Maybe I will do a few hard rear brake stops (fortunately I have a long shared private drive to do this rather than take out on the road). See if that cleans off anything. The bike sat for a while unused until I got it, so it could be surface rust. (I know what you mean about rain/rust my little Neon with probably as big of drum brakes as this GZ250 lol, does that until a few stops.)

Thanks for the feedback! I will take pics/give updates, should I need to take the wheel off for inspection.
