Rear caliper piston won't retract

Rear caliper piston won't retract
Ok, so I thought I knew about spinning the piston back in, etc., but - while admittedly I'm not using the proper little ratchet tool (my son took it to college - thanks!), both rear pistons are spinning freely using channel-lock pliers. But they're not going back into the bore. Is there something I'm missing here? I even tried spinning one with a little pressure from a c-clamp and that did nothing either. Seems like I've turned them each a hundred times - what's the trick?!
Thanks much for any help

Thanks guys, guess I'll grab another of the tools because it seems like you need three hands to hold everything and turn it back in with channel locks and put some pressure on it as well.
Is there a greater advantage to opening the bleeder at the caliper vs. the MC cap?
I'm back at it tomorrow - and thanks again.

FWIW, a tool set like this is worth its price.
They're available on Amazon and at several online retailers.

Thanks everyone - indeed it was a piece of cake with the right tool (and opening the bleeder valve). Amazing how much time the right tool saves vs. fighting with something using what may be in the tool box....
Thanks again

I used the tool from autozone to push my driver's side rear piston back in. It seems to be all the way in, but I'm not sure because it is not completely flush with the caliper. Should it be? Also, there is a hole in the boot. Would this cause a creaking noise that I'm hearing when I apply my brakes? It seems like when I apply the brakes I hear a creaking sound every time the wheels go around. Any ideas?

Thanks for the reply, Jim. All 4 of my pads are fairly new and still have plenty of life left. I used the caliper tool because it seemed as though the caliper piston was seized which I thought may have been causing the noise. After pushing the piston back in, it is still making the noise when I brake. And now I am noticing it a little bit when not even applying the brakes. It is much louder when I apply the brakes, but still happens like I said before, whenever the tires go around. So I'm not sure if the piston may be stuck again? Was thinking about just buying a whole new caliper.

I didn't change the pads so I'm actually not sure what pads they are. They were on the car when I purchased it last May. And I'm not positive if it is just coming from one wheel, but it sounds like it.
My brakes still work fine, but it's just really annoying and embarassing when pulling up anywhere in a nice car, and then I hit the brakes and it sounds like ****.
