    Some more info would be useful.

    After you use the brake it doesn't release?

    More and likely the pedal pivot is rusted and sticking. Disassemble pivot clean rust lube and reassemble..

    So what you are saying is pedal is not releasing when pressure is removed.

    Dirt or corrosion around the calliper piston preventing it from moving back into the calliper
    Remove calliper from its mount use the brake leaver to push the piston out just a wee bit and clean the piston
    Here is a link to replacing the rear pads on an evo softail all the same parts just on the other side of the bike but it should give you all the info you need
    Harley Davidson Forums

    The brake master cylinder may need a rebuild using a rebuild kit which replaces the cylinder and piston along with all the seals

    While they are locked up, crack open the bleeder on the caliper.
    If still locked up its the caliper.
    If pistons open up, it's a bad line or master cylinder.
