Hi. I havenĀ“t had this problem yet (4x M8000 and now 2x M8100 levers) but i would like to try to tune brake lever feel and bite point by this part (removing servo wave part and replace it by traight to shorten the travel). But I do not have 3D file. If someone have, can you please send it to me or give me dm here at PB? I do not have 3D scaner which would be perfect. ordinary measurig would be far from paerfect Frown thank you.

ME too! I got 3 that have failed this way.

I wonder if this part would fit. Y8VR98010

because the 8000 manual seems to indicate the lever assembly should come with one?

I don't think that's it.... I've never been able to find a part # for this piece.

Watching this! Like the idea of a modified version to do away with the servo wave as well

Same problem today after small tumble, any updates on a repair part?

Seemingly, nope....

There is no repair for it. Use it as an excuse to buy something better.

I recently had a brake failure on a ride and discovered that the master piston guide was broken in the brake lever. Rather then replace the entire assembly, I was hoping I could disassemble and use the 3D printer I have at work to replace the broken part. However, I am not sure how to disassemble the lever assembly. Primarily the post that the lever pivots on. Does anyone know if this is threaded or press fit? Is it maybe a rivot. Is there anyway to remove it?




Another one up for any news on that. Could someone send the slt file?

@SamerK I've had the piston guides fail on my M8000's and the exact same on my friend's bike too! Its clearly a design fault, or an intentional failing part. Do you have an .STL file? I could run out some replacements on our Formlabs resin printer in work...



i've had the same issue, but i make the stl they isn't perfect but is funcional. May you edit them and correct him

Seems like folks are still looking for this part. I drew it up and shared in on Thingiverse.

I've installed it and it appears to work perfectly. Time will tell how durable it is.

Nice work! Are you willing to hook a guy up with 4 out of curiousity?

For anyone looking for instructions on how to remove a lever (or overhaul the whole lever assembly), here's a great step-by-step video posted on YouTube last month: https://www.youtube.com/watch?v=gR-U3tuR0VM
