Ah i see, calipers are usually re-conned because they are cast items, things like servo's are pressed steel so i doubt it very much, plus the fact they are pressed together aswell so they can't be split without making a pigs ear of it.
Its worth a look but i couldn't stop that one i said about leaking for shit. Its the usual rubber seals story, don't last forever

Fairplay if u salvage it but i don't reckon u will.
