Hello, this is just a question in general with no specific vehicle in mind. I would like any tips on unsticking a sticking caliper that have worked for people before just replacing it all together. As my dad would say, try repairing before replacing.
Thanks, Dan

You have to realize that if you truly have a sticking caliper piston, repairing means rebuilding and replacing means just swapping it for one already rebuilt. You can't do anything without removing the piston and once the piston is removed, it has to be rebuilt.

Now it's also very common for the slides to be stuck and not the piston. In that case, the slides can be removed, cleaned and lubed to resolve the issue.

To add to already said: Replace it with already done new or rebuilt. It no longer saves $$ to do it yourself!

I replaced mine at one point just to find out that it was actually collapsing hydraulic line causing them to stick.

When flex line in in question - just bleed out a tad of fluid - wheel will spin free and that's a pretty sure diag of that issue,

This is very true. I always replace the hoses along with the calipers whenever there is an uneven wear problem. These hoses fail quite frequently.
