Default PROBLEM! Help compressing brake caliper

Hey guys,
I am an avid "do it yourselfer". I have completed brakes on an array of cars and tackled my first job on a VW last night. I am coming to you for some guidance and help...

First my friends car is a 1999 VW Passat and the rear brakes were grinding. We rented the special "tool" to compress the pistons (i guess these screw in). We started with the passanger side rear. we did not have enough room to get this tool onto the caliper, so we disconnected the parking brake cable, the spring back there, and loosened the bleeder valve. We then took some vice grips and twisted the caliper piston head clockwise, enough for us to get the tool on, and then compressed fully. We tightened everything up and went to the other side. We did the same thing but we cant seem to get the piston to compress... so i tried turning it counter clockwise, thinking it may loosen it up if it were frozen, and the piston closed more / increased in lenght... EEK WRONG WAY! so we then tried to turn it like the passanger side and it will not go back in!!! Is there something im doing wrong? Do you need to push down on the piston with a c-clamp while turning it? Is this a sign of a frozen caliper?

Also, does the bleeder valve need to be open when compressing the piston? i heard on VW's that it needs to be or it could mess up the ABS...

HELP!!!!

thank you

whats the best way, without the special tool, to acheive that? push it in by hand and turn it? or with the cclamp? when i use the clamp it makes it a bit hard to get those vice grips on the piston and turn it.

K-D Tools Disc Brake Piston Tool at BrandsPlace.com

Get that universal brake piston rectractor tool, it fits on the end of a 3/8's ratchet and will twist it right in there.

Sometimes the piston goes out to far for the piston retracting tool to fit in there. Get some needle nose pliers and hope for the best.

needle Nose does work in a pinch, but the tool is not bad to have around either.

Yes of course the tool works better...I mean use the needle nose until you can fit that tool in there, otherwise you won't be goin anywhere.

I had to think for a minute how that KD tool works, never seen one before. Obviously you choose which side of the cube fits the slot in your piston and stick the square drive in the opposite side. I guess you have to exert quite a bit of down pressure as you are turning it? I think I prefer the other tool sets with the screw and clamp arrangement at least you can use it for the front pistons too.
