Ok all fixed..........took the calipar all the way off and c-clamped the pistons....stupid rubber bootie on that lower pin ripped.
Thanks for the re-assurance fellas.
polish all the chrome, install pipes........then ride.
As a side note-last year i replaced all the brake pads on my lady.

This year just before i started my winter maint the rear caliper locked up.

Just barely got her back in the garage.

Found very light corrosion on the ends of the pistons and the tops of the piston bores. Found something that looks exactly like Scotch Brite but costs a little less.

Just looked out in the garage and must have gotten rid of the packing already.

Cleaned the bores and the pistons with this stuff and new O rings for the pistons-she be like brand new on that rebuild now.

Could just barely see that corrosion but you could definitely feel it.

Was at the 51000 mile mark for that caliper rebuild.

Hope this helps somebody.

RIDE SAFE.
