I think that's a button on the left (it pushes like a button). The plug is in there very tight. At this point I still haven't been able to remove it. This pic makes it look easy to access. The pic lies.Yours shouldn't have a button. I'd buy a centering tool, unplug the harness from the brake warning light,unscrew the brake warning light. Look at the end of the warning light switch that little Plunger drops into a groove in the shuttle to turn the light off. You should be able to get the shuttle to center by pumping the brake pedal,then opening a front bleeder while holding pressure on the pedal,I've heard of people using a small screwdriver to move the shuttle to center. I've never tried. I believe the threads on the switch are 1/2 x 20 to improvise a centering tool I'd drill the end of a 1/2 x 20 bolt a stick a piece of a nail in the drilled hole. Look on line for a centering tool,a pic and it will make sense.
So Am I correct: I need to figure out how to unplug wire, unscrew it and then use a pick or something to recenter it and then use the holder tool to bleed everything?
I'll acquire a holder tool as that sounds like it's required.
