Has anyone had their SLX (or any other new shimano) brake leak at the lever?
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.. 🙁Posted 3 years agokayak23Subscriber
I’ve had leaks at the lever (XT’s) when I’ve slightly overfilled the brakes. Pushing the pads out a little to accommodate the disc has made the excess overflow.
I’ve noticed it on occasion in use, but it’s probably for the same reason and perhaps due to the oil expanding.
I have them set up great now though. Very firm and no leaks…
No spares with Shimano. Got to buy new lever or caliper I think.Posted 3 years agoanusMember
It could be a case of overfilling as mentioned above, It isn’t the hose as I checked that and definitely noticed it coming out of the cap. I think I will give it one more good bleed and see how it goes then consider a new brake…
I bought them second hand so unfortunately warranty isn’t an option 🙁Posted 3 years agorocketmanMember
My Deores weeped for several rides from new after shortening the hoses and bleeding the brakes. There was a definite mist around the levers dust was sticking to them but the brakes worked OK. After tying them to the bars with elastic bands overnight the levers were still firm.
Maybe it was the pressure relief system mentioned abovePosted 3 years ago
