Ouch....

Those black bits were piston cups or o-rings and whatever component they
came from is going to fail fast. I would be paying close attention to
the brake pedal feel for a while, especially when holding it down at
stops....

Those bits often break off the guts of the MC when doing the 'old'
bleed. (Garages 'love' people that do their own brake flushe$$$) If
the pedal depresses way down as the bleeder is opened, it can force the
piston cups past a rust or wear ridge which can and usually does take
chunks out of old hardened o-rings or cups. The MC then usually fails
soon after.

It isn't so bad on a new master because all the rings and such are still
soft with no rust ridge.

Same thing for black bits can happen after a brake shoe or pad change.
As the pistons are compressed, bits of ring can break off which will
eventually cause a leak failure.

The black crap in the XJ's intake is CCV caused blowby starting
usually. The CCV system is very touchy on those so when the tiny tube
and 'metered' hole get a little gunk in them, the crankcase intake line
starts to feed smoke into the top of the throttle body. It will get bad
enough to start spitting oil onto the air filter in the corner too soon.

Here is a good link on that for him. I just used carb cleaner and a
chunk of wire to clean my CCV tube and a paper clip does the metered
hole in the grommet.
