    No good XT M785 Brake lever leaking from under chrome cover

    This is my second rear brake lever. The first one is leaked from the same place, would not hold a bleed. The 2nd one lasted about a season then bit the dust. If you remove the chrome master cylinder you get to the metal cover that seals the top of the master cylinder. Its leaking from around that part. Has anyone experienced this? I can see the fluid run from under the chrome cap when I squeeze the lever.
    I wish my grass was emo so it would cut itself...

    I've seen the gasket under the chrome/plastic cap fail a few times.
    Are you saying that you are seeing fluid leak from the reservoir cap?
    That's what it sounds like.
    If it's just the gasket under the cap that has failed, you can get a replacement from Shimano.
    In the meantime, you can pull the cap and apply "form a gasket" or some other type of sealant to the failed gasket and put it back together.
    You can still bleed the brakes through Shimano's funnel method with the cap sealed to the reservoir.

    I used the funnel method on those. I just ordered Saint levers because I am tired of the XTs constant weeping of fluid.
