[s-cars] Rear caliper piston: how to move it into the caliper

[John Cody Forbes]

You must both rotate and apply axial force to push the piston in, and no, you can't apply enough force by hand. Sometimes, if in a pinch, I find that it works to rotate a few runs then squeeze with a c-clamp are large pliers, then rotate again and squeeze etc. This may get the job done but it takes a very long time. Really you want/need the tool that pushes and turns for you.
