Front brake driving nutts!!!
Okay I have 2000 ultra,the freaking front brake is driving me crazy!! I changed all the old fluid out,put in fresh DOT 5,cleaned the calipers bled out real good i think and heres the problem. I can pump up the brake and it will hold as long as it stands there,I get on it and move it forward or backwards a few feet ad the brake lever sinks to the grip. I can stop pump it up and as long as its standing still it holds,I move and it sinks to the grip. I am going nutts trying to figure out whats wrong.one person said might have to be mighty vac "ed out any ideas?

RE: Front brake driving nutts!!!
Okay I said something to mechanic at HD dealership about a bent rotor and he said no. Now I think my rotor is bent because has wear on spot on it wear it rubs and then doesn't. Brake pads are wore but I don't think anyways that could add to the problem. Bent rotor to me makes sense,because brakes fail only when the bike moves. A bent rotor would shove the calipers out on a high spot right?

Check the master cylinder. \\;If you get \\;a solid brake lever on the first squeeze, let up on \\;the lever \\;just a little. \\;If it bleeds down, the master cylinder may be the culprit. If you have to pump it up to get a solid lever, it's got to be air in the lines.

Put a \\;Ty \\;Rap over the brake lever and let it sit overnight.
If that doesn't help, you can replace the O-rings
in the master cylinder (worked for me)
Even a very tiny airleak can cause these problems.

Good luck,
