Uh yeah. Must activate the rear brake service mode in the head unit BEFORE you work on the rear brakes. IMHO, screw the star all the way down and push your cup back in and then down till it stops. Install teh dust bellow. Hopefully it's flush with the caliper and your new pads will fit. Should not be as scary as it looks.
IMHO remember. I've replaced the rear pads before but NOT done this. So.. anyone else who's actually done this?
Thanks! The goal is to ultimately replace. I did disengage the electronic brake at the start however it was still slightly pressed out. I must have hit the pedal when I went to verify the electronic brake had disengaged.
