    Based on my use, I do it annual.

    It will help if you clamp the lever on bars as it'll free up both hands. Do not pinch the spring until you are able to insert the rod. If you pinch the spring it'll resist and make reassembly harder.

    what do you think of having a vacuum pump setup similar to tektro? https://www.bikerumor.com/2016/09/03/eb16-trp-brake-checks-aaron-gwin-auto-pumps-bleed-gets-aero/

    Do it while it's clamped to your bars. Inserting the pin just to keep the lever in place will help.

    ok, i've put things back together and rebled.... it's snappy again! amazing how a little cleanup has done!
  6. spyghost
    That's the plan. Also I'll be draining all the fluid from the caliper up just to start things clean.

    Nope, silky smooth

    Nope never was. Perhaps Shimano just used an old batch of piston/seal from previous levers and just whacked it in m8k? Seals are still pliable though, soft, smooth and no signs of wear

    reporting back... - without cable on the bad lever snappy return - swapped cables the good lever was still snappy, so that takes away the possiblity that the barb down the caliper being an issue. the bad lever was still slow even after a re-bleed, so this isolates the issue on that lever only i've dismantled the m8000 lever and cleaned things up. the instructions on the first page is exactly the same with the exception that there is no top cover for an m8000. when i wiped the inside of the MC, the piston and the spring with IPA, there are a few black stains that came out with the towel. could these be contributing to the issue? seems unlikely, but could it be? is the purpose of sandpapering the piston to remove material or just to clean up stuck debry?

    interesting, how can a barb/olive be bad? no harm trying since this is less intrusive. i'll report back I'm sure i used the right olive for m8k (silver) though...

    anybody ever opened up an m8000? i'm having this issue atm. removing the lever is easy buy i'm a bit unsure about the piston. The return of the lever is not snappy. See the delay in the piston? https://vimeo.com/192303047 https://vimeo.com/192303172 what's special with the shimano seals? are they proprietary shape/dimension?
