Will an Shimano M8000 brake lever blade fit a M8100? I broke my left blade, it's a Shimano XT M8100. I can only seem to find the replacement M8000 part. I don't want to replace the whole unit, seems like a waste.

Thank you!

EDIT, pics make everything better:

Here's the original M8100 lever blade:

    By "brake lever part" do you mean the whole brake lever, or only the lever blade (bit of the level you pull with your finger)? – abdnChap Jun 16 at 10:05
  • Just the little bit I put my finger on :) Is there a better term I should use? I'm a noob. Thanks! – Jonathan S. Fisher Jun 16 at 12:26

    The correct term for that particular part is "lever blade". I'm afraid I don't know if the new one is an exact match or not. They do look similar, I would suggest buying the lever blade from somewhere with a good returns policy, and buy it, compare and return if it won't fit. You can then answer your own question, and other people will know for the future. – abdnChap Jun 16 at 13:09

Ok this is exciting, I called around locally bikes owned bikes shops and asked if they had some scrap parts laying around. One of them had a Shimano SLX m7000 left brake assembly. I paid for the part and disassembled the lever. It is an exact fit. So, you can take a blade from the m7000 hydraulic series and put it on the newest m8100 hydraulic series! Fits like a glove.

KEEP all the parts from the existing brake handle! Use the existing spring, newer pin, newer retention screw, and newer rubber plug/bung!

Reassembling is tricky. I made a temporary paper pin to hold the assembling together. Then I put the assembly into place, then used the real metal pin to push out the paper pin.

    Well done! Maybe if others test with different levers, they can comment on compatibility. – abdnChap Jun 16 at 20:47

    +1 for keeping the parts... you're on the path to being a bike part hoarder like most of us :)) Well done with your fix. – Criggie Jun 17 at 5:17
