Yeah, I think it may have been Will that pointed me in their direction.
There was another place I found online somewhere else in the country, but they seemed to be way more expensive, and for what they were charging, I could just buy brand new calipers!!!!
These calipers came off an 03 Aero I believe, and were quite crusty. I wouldn't want to have put them on my car with the existing seals and pistons etc. I made a start cleaning them off with carb/brake cleaner, but they needed a lot more.
These guys pull them to pieces, thoroughly strip them down and sand blast (I think) them clean, electroplate them, then replace all the serviceable bits, pressure test them, and send them back to you.
I need the pad springs, as these ones were very rusty, but they can supply them for £8 each, so I'm going for that too.
It takes about two weeks to get them back, but I can't wait already!!! Expect more pics, ha ha!!!!
