Which won't have new pads, braided hose and fully bled..
No but you can easily reuse all the parts from the old caliper; pads, hoses, banjos, seals. OK you'll have to shell out for a new barb and olive (£2).
stuartue c (sic) - really a whole caliper for 46 pounds.
Have a search on ebay for "shimano xt caliper" - M765 caliper £33 + £12 postage from USA. Functionally identical to M775 caliper but silver rather than black. And the prices of these will likely come down whereas a Hope rebuild will likely go up (speculating here).
