    XTR brake stops working.

    My XTR 975 suddenly quit working. The lever isn't pumping any fluid...any ideas?

    A leak? Air in the line? A bleed is in order and perhaps diagnostic for a greater problem if it doesn't work.

    What's the condition of the pads?

    The pads are good. I opened the reservoir and it was full of fluid...tried to bleed but it won't pump.

    Keep going. If you have an airlock, it can sometimes be difficult to get it out the bleeder valve. If you can't, check for a kinked line, then perhaps see if the MC is pumping fluid at all. The piston's seal could finally have given up.

    Still nothing. Might be an airlock, how to get it out?

    Can you pump fluid from caliper? Does level seems to act normally?

    I'm not trying to be condescending... but do you know how to bleed brakes?

    You can try forcing fluid from the caliper up to the top (with the reservoir cap removed) by using a syringe.

    Your MC may have gone out though. You could be getting internal bypass.

    I know how to bleed, trust me.
    It looks like the dreaded internal bypass....any serviceable parts in there? Or do I throw it away?

    DO NOT throw your brake lever away! Send it back to Shimano customer service in So. Cal. I had that problem with a Deore lever and they promptly sent me a new one. Their customer service is nothing less than fantastic. I don't remember what the warranty duration is on XTR though. If you have your receipt, even better.

    I took it to the bike shop and the boys used a pressure bleeder to get it working. Yaaay!
