    Recently I hear a hissing sound when I release the brake peddle. It is
    coming from the end or the power brake servo that is under the dash and will
    stop after a short while and usually when I tap the brake peddle. What am I
    in for a fix? The braking doesn't seem to be affected.

    Thanks

    The brake booster is going bad there are no user serviceable parts for
    repair

    ...what about a leaky cruise control hose at the brake pedal
    switch.....? Booster is first choice, but I was wondering if the
    cruise control was operating properly.

    Ever bleed brakes and never have them come up very sell, only to
    remove the booster and find it was full of brake fluid? "HEY!? How
    come this booster is so heavy? Arghhh! There goes a good pair of
    shoes!" ;-)

    Jay,

    I also have this problem on my 2001 V70 XC. I just bought it, and am
    new to Volvos. Can you tell me what happened with yours? What ended
    up being the solution? Any advice would be appreciated.

    Thanks!
    Jeremy

    There are no vacuum parts in the cruise control on the ETM (electronic
    throttle module) equipped cars (1999-). And this chassis (S80, S60, V70
    new style) has frequent failures of the brake booster in this manner.

    Replace tt with t (twice!) and remove parentheses to email me directly.
    (But I check the newsgroup more often than this email address.)
