This thread is less of a 'how to' more of a 'could you guys/gals watch over my shoulder while I do this and give me some helpful advice and/or scream insults at me for doing something stupid
The idea is that it's a learning process for me, if I do screw em up then it may be £40 down the drain but hopefully I will have learnt something along the way.
I wanted to completely refurb some calipers, learn how it all goes together and end up with something sparkly
I cant afford the time off the road to do it on the ones on my car so I bought these from AutoLusso (Thanks guys!), shame really as they were in quite good nick
I do plan on getting someone responsible to have a look over them when I've finished to ensure I've got it all 100%
What I got.

Ok so I pulled everything easy apart, keeping all the bits safe, in hindsight doing this on the kitchen table was a mistake, these things hold a surprising amount of brake fluid even after being off the car for a while!

I dont have an air hose to push the pistons out so I've been (very) carefully pulling them out by hand or with some covered mole grips, being careful to keep the pull square on. You can see where I've got the pistons out to. They dont seem to want to come any more (on either caliper).
I read on another site you can get the dust jackets off before getting the piston all the way out, anyone got a recommendation? The dust jackets look in good condition, no rips or holes so I'd like to keep em in one piece for now.
This one also has a chunk of brake pipe attached. I can see why! It wont budge. Soaking in WD40 now. The sliders are also on solidly. I've got to try to get those off too.
Thoughts, comments and ideas welcome
1). Get the pistons out
2). Seperate the dust jacket and o-ring and clean.
3). Clean up the pistons
4). Find some nuts to go into the brake line holes to keep them clean.
5). Degrease the whole thing (Can I use Gunk spray on them?)
6). Order some new nipples (Mmm)
7). Clean up with a whirling wire wool brush thingy.
