    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.

So I was taking apart my master cylinder to clean it up. Any chance that there's a good write up for this. Also the little boot. Does that need to be intact? I noticed a small tear in mine. The bike is a 77 750
 
Most motorcycle master cylinders are very similar just watch a couple of you tube videos and dive in: https://www.youtube.com/watch?v=0mTi4Pitk4M.
If it were me, and I didn't know when the brakes were done last, I would go ahead and put new OEM seals in it. It is possible that it would work just fine with the current parts, but your brakes are pretty important.
Take pictures as you disassemble.
 
When you get it apart use a flashlight and inspect the bore for pitting in the aluminum. Pitts = junk master. Sadly, water in the fluid often leads to pitted metal but hopefully that doesn't apply in this case.
 
Thanks. I'm having trouble getting the little snap ring out. I'll let you know how the bore works once I'm back at the garage with the proper pliers
