Happy new year
you can try this
loosen the bleed screw on the caliper using a c-clamp try and retract the pistion
once you open the bleed screw it will take any pressure of the caliper and it should go in easy

if it is binding in anyway then you will have to replace it

if the caliper is still on then you might have to put a screw driver between the brake pad and rotor (not the piston and shoes as this will damage the caliper piston
and pry it a little so you can remove it then use the c-clamp like i mentioned above to retract the piston

i usually use the old brake pad between the piston and c- clamp
if that helps you please press accept and leave feed back thanks

Happy New Year! This caliper has a screw in piston does that make a difference?

Yes it does make a difference
sorry miss read your post
do you have it off the rotor or is it still on ?
