seized rear caliper and pad pins 98 vfr800

Hello,

This weekend i got around to trying to find out why my rear brakes were dragging. upon removing the rear tire and looking at the calipers i saw the pads were un evenly worn on the left side of the rear caliper. So i tried to remove the pad release pin to get it out and to no avail it was stuck. So i checked my full service manual and saw i could remove the caliper as a whole so i did. I did so by taping the caliper gently down because their was still pressure on the rotors due to the piston being stuck.

With the caliper of i realized that not all piston were seized but only the middle larger one. the smaller end pistons pushed in normally but i cant get the middle one moved.

my question is can i just put a C clap on it and push it back in or do i need to crack a bleeder valve to get a release in hydraulic pressure. i don't want to damage any other part.

also any suggestions on removing the release pin for the pads. i have some vise grips i can try. i sprayed wd-40 on it last night in hopes that would loosen any rust.

i plan on flowing up the repair with a brake system flush. the rear disk is still in service range according to the manual and my dial calipers.

thank for any help,

I cannot speak for my VFR, but I use a C-Clamp to reset my calipers are my cars (Ford Contour and a Porsche 944T). I just place a 1x2x3 inch piece of wood between my caliper and the C-Clamp. Works like a charm for me always.
