    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Help with mysterious brake noise, '78 550

On my '78 550, the front wheel makes a clacking sound in time with the wheel revolutions when the bike is cold. Seems to come from the brake caliper. The sound goes away if I lightly apply the front brake. I'm running the stock rotor, caliper and pads (replaced last year). The caliper and pads move freely, and the pads don't drag when the brake is not applied, but I haven't rebuilt the caliper.

I can sometimes hear a trace of the sound in the shop, if I elevate the front end and turn the wheel slowly, but I cannot determine the source. I can't feel any roughness or burrs on the rotor, and nothing else is rubbing or striking when the wheel turns.

Anyone have any suggestions?
 
Does the caliper wobble on the pins? They, or the holes they fit in, could be worn. Also worth checking to see if it's the speedo drive as that's not far away.
 
Worn out or missing orings on the carrier pin, slightly warped rotor, loose outer pad retainer screws.
