Rear disk, resetting e-brake

I cant reset the piston in an in-caliper e-brake set up on the back of my '03 accord. I have the special tool but the thing just won't turn. Any advice on this vile, hateful, retched abomination of a set up?

Piston won't turn? Caliper is seized.

Sometimes its a real bitch to get the piston to start turning. It's even more fun when the tool you have just barely engages the pin holes (MINI's...)

I'm not sure which tool you have, but I've had limited success with the little cube thing.

I had the 10 pc rental set from AZ. I finally got it after finding the right way to lengthen the handle(12mm socket w/extension), heavy gloves, and being hell bent on getting this horrid job done.

One pad was metal on metal, but the rotor was not too far gone, thankfully. The other 3 had 50% left Because I wanted to return the tool ASAP I sucked it up and did both sides last night. While I was in there, I also went for a tire rotation. All this out on the gravel driveway at night with my light coming from the headlights of my car and a mini mag. I was finally finished at 2:30am. The things we do to take care of the ones we love.

To have one pad worn significantly more than the rest means you have a sticking piston or slide. Sanded, polished and lubed all the caliper slides?

...or just get new calipers, because they will fail/stick again much more rapidly than the first time.

I've done this on my race cars as I will wear out a set of rear pads much quicker then on my street cars. The race car also is not exposed to rain, snow, salt, & cold weather so I have no problem re-setting them.

I have decided never to do them on my street cars but to pay the money for rebuilt calipers or even loaded calipers and be done with it and not have the struggle that you had.
