    Default Ktm brakes won't bleed? Help

    Hi Got. An 07 Ktm sx 125 and I can't get a rear brake, tried the conventional way of pumping up the pedal and releasing the nipple, also tried to back bleed but the fluid wouldn't go up through, at one point got a very slight brake, any suggestions, cheers

    Take the brake pedal off and back bleed it, the lever will be tight i bet so its slightly on all the time, hence the reason why the fluid can't be pushed back through

    Took the lever off and back bleed it.. Still nothing won't even push the piston in the caliper out.

    The piston is most probably jammed full of ****, try and get them out and clean it up, then try it

    When you tried to back bleed it did you take the rear master cylinder cap off ?
