My Honda Accord just hit the magic 100,000 mile mark and now
all sorts of things are beginning to go bad. The latest problem
I am experiencing is with my brakes.  They still stop the
car fine, but once I am stopped completely, my brake pedal
will sink another 2 or 3 inches all by itself.  If feels really
strange, and I am worried my brakes will quit working one of
these days.

I checked my brake fluid, and the reservoir was full, but the
fluid itself looked really dirty (like dirty oil).  I called
my mechanic and he told me I need a new brake master cylinder,
which will cost me a whopping $250-300.

I was just wondering if anyone out there has experienced this
sort of thing.  If so, is my mechanic being honest? Or do I
simply need to have my brakes bled and new fluid put in?

Any help you could provide would be appreciated.  Please send
replies directly to me, as I rarely have a chance to read this
list.  I will post the responses if there is any interest.

Thanks,
