    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.

Please Help with Brake Caliper Identification

When I bought my 79 GS850G the PO gave me a box of extra parts. There's one rear brake caliper and one front brake caliper. I'm wondering if they're from a 79 850 or later year. I'm wondering if one or more of you fine GS lovin folks can help me identify them.

FRONT

REAR - The only difference I can see with this one is that it's stamped with an X8 in the rear of the caliper vs. the stock caliper on my 79 is stamped with a K6.

The front is the round puck type which was superseded in 1980. The rear caliper fit many years, including into the 1980's. You can look up this sort of info on partzilla. Their listings show where used.

Ok, I thought the front looked just like the ones on my 79. Great, thanks for the heads up on the parts site Ed.
