Thanks. I will check them out if I ever get the stuck piston out. Where did you buy them? (fudge answer so forum software doesn't delete it!)

May need new pistons if the groove for the boot is corroded or damaged during removal. That and the corresponding groove in the caliper are likely where moisture and salt get in and cause corrosion at the end of the piston and cylinder.
