Tbh I would have stuck with the xt 765 brakes I had, but the pistons were seeping and contaminating the pads - couldn't get replacement seals or calipers so ended up with the new brakes
First off a tip for contaminated pads-
Buy a blowlamp, nothing fancy one of those kitchen ones is more than sufficient.
Place the contaminated pads onto some heat resistant surface like the cooker and heat the pads up. This has the effect of burning off the solvent(if hydraulic) or the fluid itself(if mineral).
You are not trying to heat the pads up to their red hot just enough till the fluid/solvent starts smoking. Also dont keep the blowlamp permanently against the pads as this will heat them beyond the point where they can separate from the backing so carefully does it.
After that you want to sand the pad surface using a bit of fine wet&dry(not sandpaper) To do this well its best you place the wet&dry on something like a piece of glass or a spare tile as these are perfectly flat. sand toil its a uniform colour because of the roasting you just gave them. You see exactly what i mean as you start to sand them.
Fit and away you go
Bit late now as youve made yer bed
I happen to have some shimano XT m765 brakes in my spares box. They consist of new left and right levers and one new caliper. I've fitted the caliper to the front lever and am hoping another brand new m765 caliper turns up eventually. However, I also have a new rear shimano saint m800 rear brake[caliper/lever] and apart from the colour are totally identical to the XT stuff. I've been considering putting the saint caliper on the XT lever and looking for a home for them
The levers arent a mach via the numbers .One is m765 the other is m756 Theyre both XT levers and are identical in every way except the m765 lever cover says shimano XT the m756 lever cover just has shimano on it
