I learnt about this when doing rear disc brakes for the first time. Rear calipers have a thread on the piston which is needed for hand brake adjustment as the pads wear. So the tool will push the caliper piston in whilst turning it in its thread. I managed with out, by pushing the piston in with a g-clamp a bit at a time whilst using pipe grips on the very end of the piston to turn it in on the thread.
Note thread is very loose affair it felt like the ones on the top of a jam jar, so by pushing the piston in a bit it you got the thread faces a part so you could turn it till up against the thread faces again. Give it a try.
Note a thread on a jam jar abit like that on rear brake caliper pistons :lol
