    How can i fix leaky brake lever?

    So, after being real scared to put on a hydro cuz i dont know anything about them, i ate it pretty hard today, and bent up my brake lever pretty bad. The brake would not let go, and the pads did not want to pry apart, and by trial and error i let a tiny bit of oil out and that solved my problem, in fact made it a better feel than it was previously. the interesting part is throughout the rest of the ride i thought the brake feel was changing/ getting mushier, and when i stopped and looked at it, lo and behold, there was a little leakage happening in the brake lever region. from the general are where the red arrow points.

    as much to the otherwise as anyone says, this is part of the reason why i will always prefer mechanicals, but after getting this for $20, i couldn't resist.

    if its possible though, please edjumacate me on how (if its possible) to make this better. youll be my hero for the week.

    thanks

    Sorry I'm no Magura Guru but my guess would be the master cylinder seal failed. Hopefully a Magura expert can chime in and help out.

    Dont give up on hydros they are awesome but when you buy used you get what you get unfortunately.

    yeah, it was a brake that one of my friends had never mounted after it was warrantied for him, so even though it is older, it has been run on a bike less than a month total in its life. oh well.

    Guess nobody know anything about Magura brakes.

    Your LBS can order through BTI also navigate through the Magura Flash site they claim if you sign up you get Free CS wow thats mighty generous of them.

    Magura's are tricky to work on. And they do not offer up a seal kit. You have to by a whole new lever/pump/master cylinder whatever they call it. You can take them apart but it is not real easy but, can be done. You might have too much fluid in the system, which you already discovered. Now you might have introduced air into the system. Do you know how to bleed your brakes? Read the manual carefully. I'm not familiar witht the Louise but the Martas were fairly easy to "gravity bleed".

    sweet thanks. i dont have the manual, i got it from a friend when i was in a bind and needed a brake for the weekend. i think the brake is from about 2003 maybe? i dont know, it was an old warrentied thing from him that he never mounted, and he gave me an mx-4 and that out of his junk bin for $20. I figure the 7" rotor, mx-4, lever and housing are worth 20, so whatever.
