SableOHC, actually, the cube won't fit the rear rotors. Trust me, I've been there too many times. And the pliers substitute works, but it reeeeallly really sucks when the pliers slip, and you tear the piston boot so badly that you have to replace the whole caliper. <_<
AutoZone sells a brake caliper reset tool kit that has the right sized tool for the caliper that makes the whole job a bazillion times easier, resulting in you cussing and swearing a whole lot less!
Well, I cussed and swore a whole lot less.
Oh yeah, you want to turn clockwise, and push while you're turning. Bleeder valve open makes it tons easier, but will require you to bleed the brakes when you're complete. Which is something you shuold be doing, anyway.
