Keith,
I've noticed on my motorcycle, that the fluid gets a grayish cast to it in
about two years of use. The BMW book recommends flushing the system every two
years. I assume the fluid pulls moisture out of the air into the system over
time then the fluid gets contaminated. Yes, it's a lot easier to evacuate on a
motorcycle.
Did you flush the system out completely or just top it off and bleed it? Of
course if you blow the system out with air it will be one pain in the %$#@ to
bleed your entire system again. It can be done with the help of a Mitty Vac
brake bleeder.
I may be wrong here, but I feel as seals get older some of this stuff in the
system may be from the seals.(?)

Subject: Brown flotsam in brake fluid
I have brown colored flotsam suspended in my brake fluid reservoir! I
assume this stuff is moisture that got in the system/fluid somehow. I have
done brakes before and never seen this happen. Could it be something else?
The fluid is otherwise quite clear, the only way I noticed the flotsam was
because I had to open the cap to see if there was fluid in there. Last
month I rebuilt the MC Piston and honed the MC, and bled the brakes using a
new can of Castrol DOT 3 - 4 brake fluid, ensuring I got good clean new
fluid at each bleed nipple.
