Rear 2 pot calipers - to split or not
I've removed my rear 2 pot calipers because of seized pistons. I have a refurb kit but it is worth splitting a caliper that has no leaks so that I can clean it easier and better. Or would you just clean it as best possible while it's all sealed and has no leaks.
Also should I just clean it up with brake fluid or should I use the proper parts washer at work? I'm concerned that using the parts washer may mean water ingress. Any advice on the return would be appreciated.
Thanks

I split mine so that I could replace the O rings. If you are making the effort to rebuild them, you may as well do everything. I cleaned them with degreaser solvent, then painted them with VHT paint. If you clean them before splitting or removing the pistons, you're unlikely to suffer an ingress. They are easier to work with (replace pistons/paint etc) if split in half. I fitted stainless steel pistons. I found it easiest to attach them back onto the car in order to tighten the bolts holding the 2 halves together.

Thanks for the comprehensive reply. I'll split them after a good clean then. It means I can ensure they are super clean and I'll see if I can get them sand blasted at work to prep for painting.
I've managed to order new pins, rattle plates etc so I may as well go all out

Thanks both.

I would personally say you're less likely to end up with water anywhere you don't want it if you split the calipers as you can blow directly through the crossover holes to clear them out.

Thanks all. I split the calipers and gave them a good wire brush and clean up, dried it all with the compressed air. Painted and rebuilt them.
All looks good so far.
