    Help with changing brake levers

    I was on a ride last week and had a crash and my brake lever snapped. It did not mess up anything but the lever, I can pull what is left of the lever and the brakes still work good.

    I have a 2013 Trek Mamba with Hayes Dyno Sport Hydrolic disc brakes.

    I looked on Hayes website and saw these.

    Carbon Lever | Hayes Disc Brake

    Only question I really have is how to take the old lever off and put these on. I was looking at the brake assembly tonight and could not quite figure it out. Has anyone done this before?

    If you look at the picture on this link

    Dyno Sport | Hayes Disc Brake

    You can see the black part that is screwed on, when I took this top off I could see the part where the lever pivots at but did not know how to release the lever or take it off.

    Thanks for the help in advance

    I did a lever replacement once on a old set of Hayes on my son's DH bike, is tricky but doable. Don't recall the model (HFX Carbon?) but the lever was attached to the body with a bolt and to a push rod in the master cylinder with a nut inside the lever. You screw in the push rod and then attach the lever to the body.

    Verify that the carbon lever is compatible with your body, sometimes they do but sometimes they don't.
