    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...

    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.

Front master cylinder cup set stuck

My cup set piston has got jammed inside the front master cylinder. Anyone experienced this and have any idea of extracting it without damaging the interior?
 
Only way I know is a compressor to blow it out, but make sure you got towels or something in front to catch it.

Are you thinking of the caliper?

You can stick a dowel in the other end to push it out.
 
I did that for my caliper, but I figured the same would apply for the master cylinder...

It didn't work for mine mind you, but that's a whole different story and it was shagged completely...
 
Soak it in pb blaster and just work at pulling it out. Maybe put the system in a vise, protected of course.
 
putting it through a compressor might damage the oil eye port wouldn't it?
 
No, it's just pretty good air and it will help clean some of the big junk before you start working the brake cleaner on it.
