they will need a refurb as they have not been used a couple of years so the pistons may be stuck.
hence free to anyone who wants to come and collect them if they are of any use, perhaps for a project of some sort which needs brake calipers.
audi put a new set on my car as the brake cables had caught something and twister and they didn't want the reuse them.
