Shimano lever diaphragm replacement
HTML-код

- If you ever overfill shimano brakes and accidentally over-pressurise them, you can have leakage from the end cap - this is oil escaping from the diaphragm. There's limited info on the web, so I made this video to show how it is possible to replace the diaphragm.
Also worth noting: I discovered that o theory it is possible for the diaphragm to leak without puncturing too.
*disclaimer* at this point in time I have not checked the brakes on the trail extensively, but so far they are doing well.
I inspected it and mine had a small pinhole in it. The plastic it wad covering had a small mold defect and poked a hole in it. Thank for this very informing video. Without I would not have been brave enough to tackle this. Cheers
You're welcome! - Glad it helped, well done
Im replacing mine right now. I took off the lever and the plastic shim underneath where the metal dowl pin goes. Its much easier to access.
I found myself in the same situation. I couldn’t find the part for the XT brakes but I found it for the XTR. Slightly different but I thought it was worth a try. I just finished it and about to install it back on the bike. I see that you also have the XTR part which is slightly different. Any issues long term?
Not so far - definitely some differences in fit but no leakage as yet.
I am going trought the same problem. My brake is a XT M8000 and I just can find for M9100 (as the vídeo) and for XT M8100. I just cant figure out if fits well.
@@gustavoebo9002 I’m not sure about the 8000-9000 compatibility, but I can confirm that the 8100-9100 are cross compatible
@@ariskardas thanks for confirming that - it will help others on this thread
What is the part number for the diaphragm for a Slx M7000 lever
@@valyuson7594 I used the M9100 part - the packaging has a bunch of numbers on it. I think the part number is: Y1XJ98030
Which XT is yours? M8000 or M8100? The diaphragm fits well, dispite the pachage says M9100?
Hi there, thanks for the video, where do you get the diaphrams from?
They came from ebay - here's a link that will get you to the right search page: www.ebay.co.uk/itm/226091151764?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=uapkhczhs6i&sssrc=4429486&ssuid=E9nmNkuBRt2&var=&widget_ver=artemis&media=COPY
They came from ebay - there is a lot of choice
NOTE if ypu only release the grub screw rather than remove it you wont have the same issues replacing it afterward!
Have now been running this lever for about 6 months, as a guide: take it from me; this has worked - good luck folks!
I can find the grub screw on the slx but not xt ?
It seems to not necessarily be a slx or xt thing, but the version - I'm afraid I have an XT lever with the grub screw, and one without...
