SA22C front caliper rebuild - stuck piston

Any tips or tricks on getting a stuck piston out of a SA brake caliper? The compressed air wont even budge it.

Large grease fitting threaded into caliper where brake line installs will allow you to use a grease gun to pump grease into caliper. Hydraulic force will slowly force it out with no damage to it or caliper. Fair chance the piston is pitted and rusted to the bore in caliper,you won't know that til you have the piston out.

You'll need to remove all the grease from caliper and wash caliper in solvent to remove all traces of grease so you can inspect caliper bore.

If you end up needing a set of used SA calipers. I just removed mine and I think we could work something out.

Sounds like a good alternative.
