I've got another Hope to give the Muel treatment this week, so I'll make a video or a wiki with pics. But for now: should i strip the whole brake down and put new seals in it? Yes, unless the old seals arn't leaking, and even then I'd do it anyway so it's done. or would just a good clean be in order? See above. is there any way of getting the bore cap off other than the tool? Yes, get a piece of stell, file it down with the two edges rounded until it will fit across the bore cap, put this piece of steel in a vice, mount the caliper to a fork or a piece of steel with a caliper mount cut out of it, thenwith one hand press the caliper down hard, and with the other gently undo the bore cap. if not...does anyone have one that i could possibly borrow? Nope, sorry. But making your own is piss easy.
