I got 2 front brake calipers from a 307 HDi 110 (same as GTi180) on ebay for the grand total of £21 delivered.
They look in need of some tlc though, I'm going to make a little project of refurbishing them. I want to strip all the crap off them and paint them myself and then send them off to have all the parts renewed
I just wanted to know what you would recommend for getting rid of the caked on crap, and do they look within repair?

To get the crap try something like brake cleaner and a wire brush/wire wheel drill bit, screwdriver to help chip off any tougher bits. If you really want to go to town on them you could take them to be sandblasted.
They seem to look in good condition, are the bleed nipples free, that can be the bigest problems with calipers. But if your sending them off to be refurbed they should could back like new.

Thanks for the replies
I bought them because I thought I would never come across another pair so cheap
Bigg Red also do a refurbishing kit for £30 and a new piston is £17, but I wondered if it is easy work for someone who has never done it before, and what tools I would need

Do they need mechanically refurbishing? I doubt they need it. Just get a wire brush on a drill, sandpaper or partly scrub them in turps or similar.
Then spray them in gold Hammerite. Spray the none friction surfaces of the discs in silver Hammerite. Then they will look as good as mine...

Well it seems I can do this making use of the paints and tools I already have for a lot less than £150, even including the money I paid buying the calipers
Thats a good guide thanks, I'm not sure what an airline is though
I will be buying brand new disks and pads for when I put them on well into next year, I would be dead pleased if they looked half as nice as Edwards!
Edit: You can see the iside of the pistons look quite rusty, would I be okay to sand them out a bit?

You can sand them yes, Or just coat them lightly in copper grease. They won't get any worse.

if you are stripping them, get some bilt hamber deox c. Wire brushing, then put the calipers in a bath of Deox C overnight produces some fantastic results and will give you a great prepared surface to either powdercoat or paint etc and means you're not taking away excessive material too using power tools.

Thanks for all your help so far guys  Deox-c appears to be quite inexpensive too!
When putting the new seals on, and the pistons back in would it be best to give them a light coat of brake fluid?

Ok so after trying brake cleaner and making no difference whatsoever, I've bought a tub of deox-c and the calipers are chilling out in a container of the potion right now, I'll post back to this thread with some progress
There are some really amazing results on detailingworld with this stuff, and even if it doesn't help with the caked on stuff on the caliper body, I'd be happy if it unseized the bolts and cleared the rust inside the piston

Did you submerge the full caliper in Deox-C?

Yes it sounds risky I know, but I will be replacing all the seals and in the worst case scenario where the calipers are completely ruined for some reason it's not like they costed a lot and my car isn't off the road as these are only a spare set to have a play with
I did phone up a sandblasters about getting them done that way, but they said they would be hesitant to sandblast calipers
Edit: Deox-C on calipers has been done before

Update: The calipers have been in for around 5 hours now, some of the baked gunk has come off to reveal a nice smooth surface, the rest has softened up and comes off with a bit of work from the wire brush. The water is really dark now because of how bad they were, I'll renew the 'bath' tomorrow morning and leave them till the evening, hopefully with a proper scrub they will be ready for photos to share on here
