preferably in the midlands ,or should i buy a seal kit and refurb them myself ?

Depends whether they need new pistons as well or not. If they need new pistons (many times they do) then its pretty much as cheap to get refurbed calipers.

I get all my stuff from CAS (Central Auto Supplies) who are midlands based and pretty good prices if you ask them for trade discount (you can usually get it)

cheers 38 each exchange price,i better blag a discount now

I don't know if they're any cheaper than CAS but Brakes International are pretty good:

they are good, but you have to watch how much the postage adds. Their website is VERY useful in sourcing appropriate off the shelf discs, calipers and mastercyls for specials though!!
