rich the front calipers too ages as buffed them to the bare metal so no rust lumps just looked as they should when new,i removed the piston and seals taped up the chamber used a old brake hose and bleed nipple so no paint got inside and gave them about 6 coats of paint the back caliper got the wire brush on the drill and most rust build up removed with a toffee hammer and 2 coats but does not look as smooth as the front ones.but will take my time with other rear one next weekend
