Do the pistons in the rear calipers of the S197 have to rotate as you push them back in?
Spank you.
Spank you.
It should compress itself as you spin it. My tool ( pictured below ) you just put it on an extension and crank away with not much downward pressure.
+1 would have worked in this situation...The answer is no. No compression is needed. You can just grip the outside edge of the piston and spin it clockwise; it will collapse as you spin.
