both calipers are free and working fine, I can compress them easily and they seem to work fine. no power booster just manual breaks and no headers..yet. just the (as I call them over slung manifolds). gonna flush the system and change the flex hoses as everything else is new (at the wheel). there dosent seem to be any drag when they are cool. I was thinking the flex lines as well , they don't seem to be weather cracked but they are old (probably 6 - 8 years)
