if the piston is seized, then it will need stripping & cleaning up. exchange ones are fairly cheap.
if the piston has been pushed out a long way, you can get them back in with careful use of a g clamp

I'd advise getting a pair of 2nd hand calipers from a scrappy...

its mroe that if you try lubing a caliper with WD40, it miplies you dont have the ability to refurb your own caliper lol

[mowgli]

if it is seized, then there is a good chance that there has been metal on metal. and that simply isn't good on a brake system

use a grease gun on the bleed nipple to push out seized pistons
