I have a set of shimano SLX lever zee caliper brakes and for some reason the back level leaks. It keeps leaking at the lever and then taking in air.
It seems to be coming from under the big cap (the one that usually says slx/xt/zee or whatever) so you have this plastic cap, then the metal plate, then the sort of plastic/rubber insert before you actually get to the reservoir and fluid. It seems to be that the liquid is coming out at the point but when I take it apart it all looks totally fine, no wear, no breakages, all seated nicely yet it still leaks.
anyone had the same? and can you replace only the internals of the lever or is it new brake time? I think that it is also leaking at the caliper at one of the (4) pistons as it may be cracked..
