I've got a pair of dual piston calipers w/ abutment brackets up for sale along w/ a pair of rear disc calipers w/ abutment brackets. One rear caliper had the bleeder screw break off & then I broke off one of my extractors in it. Either you can try getting the screw out OR use it as a core.. either way I'd like $60 + shipping for all four calipers w/ brackets. Let me know!
