    I have an 05 Night train with no front brakes and I can't figure out why. I had just replaced my stock levers with some aftermarket black ones when my front brakes locked up. The piston in the caliper was not frozen, so I pushed it back in, but, at that point, I had no pressure in the brake line anymore. I'm no brake specialist, but, I do have a little mechanical eptitude, so, I disconnected the brake line from the mastercylinder to see if I have any pressure coming out of the mc. I did not. To make a longer story shorter, I bought a rebuild kit for the mc, installed it, and nothing changed. My father in law had an extra mc that was like new (he had changed in out for chrome, and it worked when he pulled it), I tried that, and I get nothing out of that mc either. It's like the mc hasn't been primed or something. The only thing that I haven't tried is to reverse bleed the system. Does anyone have any other ideas?

    Does the m/c need to be bench bled? Maybe that's where my problem is. And if so, if I reverse bleed the brakes, will that bleed the m/c at the same time?

    By reverse bleeding then you push the fluid in through the caliper bleeder up the pipe and into the master cylinder
    as i use a large syringe and some clear tubing to do this it only takes about 5 minuts and as the fluid goes up the brake pipe then the air is pushed ahead of the fluid and exits the system through the master cylinder resevoir so the cover of the resevoir heeds to be loose to allow air to escape

    The lever I had bought apparently was not specifically for my bike. It kept the brake cylinder pushed slightly inward which kept it from priming. I filed it down and now it works fine. Thanks.
