x2. I used to fiddle around with rebuilding calipers, but the time and unpredictability of the repair just don't add-up compared to buying a new one.

It was always a time-consuming problem to remove stuck pistons. Most of the time the calipers were un-repairable. The problem is the corrosion of the bore and piston. The bores can sometimes be reconditioned with fine sandpaper, but the pistons are chrome-plated and any corrosion of the chrome means a throwaway.

If they are frozen, they are junk.
