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

[Jerry Scott]

Try cycling it in and out a few times; it should eventually go all the way
in.  The corrosion is probably limiting the travel.

  I have this "cube" tool.  I rotated the piston clockwise and it does 
not go in.   But counter clockwise rotation quickly move the piston 
outward.   Can it be that it does not go in because I can not apply 
enough pressure on the piston with my bare hands?    I am afraid 
something is off inside because the piston had to extend a lot,  the pad
wore out to the metal backing.
