    Brake fluid

    My 997S is 2 yesrs old with less than 10,000 miles on it.
    Do I need to replace the brake fluid for the 2 years service?

    Re: Brake fluid

    Yup, need to replace it. I get mine replaced in a few weeks.

    Re: Brake fluid

    Yes, it absorbs water (I dunno why) and the next result is brownish stains on the inner workings which are really corrosion which is slowly ruining the tolerances/precision of the _expensive-to-replace_ brake components.

    This is an easy and fun DIY if you buy a Motive power bleeder and some fluid. Total cost about $75...

    Brake fluid is hydroscopic, which means it is a substance that absorbs water from it's surroundings, in this case the humidity in the air.

    Re: Brake fluid

    A hygroscopic substance readily absorbs water from its surroundings.

    (Note spelling)

    The similar sounding but unrelated word hydroscopic is sometimes used in error for hygroscopic. A hydroscope is an optical device used for making observations deep under water.

    Yeah, but WHY? darn! Don't want to sound like a kid (why,? why,? why,?) But I assume it is petroleum-based product and I thought roughly "oil and water" don't mix."

    Seems like we should *never* have to change brake fluid, should stay clean and almost sterile (kidding) since the system is completely closed, except for a tiny vent somewhere.

    Could you give a brief description of how it's done,
    type and quantity of brake fluid used , tools needed etc.
    I would appreciate it ,
    thanks.

    Re: Brake fluid

    jcs, there is a good article in renntech.org

    http://www.renntech.org/forums/index.php?showtopic=7064

    the steps are same for 996 and 997.

    You're right, been mixing the "d" for a "g" for years.....

    Re: Brake fluid

    The manual recommends clutch fliud change at the same interval.
    Has anyone done this procedure by themselves? is it hard to do?
