Get a manual on that model of Opel and it will tell you what to do!!!!!!!!!!!!!!!.
i would take a guess that you are working on the rears? if im right that piston has to be rotated in order for it to go back in to make room for the new pads. rear calipers on a rear disc setup are kind of like a screw, so rotating them will make them go back in. direction im not sure of but you will know if you are going the right way because the piston length will get shorter, if your going the right way. if it gets longer rotate the other direction.
