Afternoon all

Next weekend im changing the brake calipers on my Spesh (found some mint 2nd hand 4 pot XT’s on ebay).

How much mineral oil would i need to fill both front and back brakes ?

Both brakes have been supplied dry. I was going to get the smaller kit from Shimano, but i don’t want to get it all fitted and realise i need more oil.

Any help would be appreciated

    Not much at all, unless you get carried away.

    A small bottle (i.e. 200ml) will be enough for a couple of full bleeds on both brakes.

    The resevoirs only hold about 10ml (at a guess) and there can't be much more than 20ml in the rear hose. Who knows though, I could be miles out, but I do know that I have never out of brake fluid!

    my shimano xt 775 came with 2 small bottles

    Was enough providing no spills and as long as you know what your doing.

    Halfrauds do a bottle for about a five or six quid and i havent noticed any difference

    good luck
    If you fall off try again !
