stubborn Rear caliper

[bigdavet]

Me again.

Decided to rebuild the rear brakes while everything is apart. Is there a trick to getting the pistons un-stuck? (Pic coming) I've got the kits, new lines, chomping at the bits to get this rear end back together.  Thanks for any help

I have used both compressed air and a grease gun.  If using air wrap towels around it!

Thanks for the reads. It's already done.
