Shimano brake query
shouldn’t do that from new, uless they’ve been rebled at some point and are faulty, or the seal has not seated correctly. I suppose needing a rebleed is one thing. Leakages from new would concern me tbh, unless it’s simple. I’d get in contact with them first before they become used goods. They should replace them, as long as you do not start trying to fix them.Posted 4 years ago
Just fitted some new SLX brakes from Rose so did the lever swap today.
One brake is very spongy, so presumably I got some air in their, and assume a bleed will fix that.
Now, the other one is very firm, but some oil leaks out of the reservoir every time the brakes are applied. Will a bleed sort this out as well, or does this mean the lid is a bit loose? The reservoir needs a small hex plus a small Torx to tighten it.

I think it would be perfectly reasonable to try tightening the reservoir cap before declaring it knackered…. A load of hassle to post them back, when it may just need nipping up. You’ve shortened the hose, so its already used. Try and fix them unless you are a complete ham-fisted bodger 😀Posted 4 years agoduirMember
I had leaking fluid from my new XT brakes from the master cylinder after a cut and re-bleed. The brakes felt great with loads of bite and not spongy at all. So I spent a few rides wiping away the fluid and after 2-3 rides it stopped and the brakes have been perfect ever since.I read somewhere that it’s easy to overfill on bleed and there is a function to allow seepage. Also undoing the bleed port raises the cap a little and that allows a little overflow.
Do a re-bleed, then check the torx screws are tight and the connectors done up correctly.Wipe away the excess for a few rides and see if it stops and the brakes still feel fine.
If not they are knackered.Posted 4 years ago
