I have some low use zee calipers that were removed by a bike shop. Tried to reinstall them today and they're both leaking, so badly that when I remove the lever bleed screw the oil flows from around a piston out under gravity. All pistons looks to be in great condition, calipers worked well before removal.
Any ideas what has happened? Conscious the seals aren't user serviceable.
