Re: Flushing brake lines
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.

Re: Flushing brake lines
Welcome back Mike,
The larger floaters were in the master cylinder when we siphoned it out
before starting the flush. The procedure we used was that the master
cylinder was siphoned, refilled with fresh fluid, and then "pumped" through.
There were some tiny specks in the drained fluid but the larger ones (but
still very small) we removed by siphoning beforehand.
I don't know if it is related but Ed's fluid reservoir was coated in a layer
of ....slime (for lack of a better term)
As for the cup/seal wear I guess we will see what, if anything, happens.

Re: Flushing brake lines
He should be expecting to do a MC change soon.....
Oh, so I ran into some 'local yokels' up there camping and for sure they
were the same ones with the ------- mouthy dog as when I/we were in the
bush and these fools were likely jerking your chain for directions.
A bunch of years ago the government changed the name of the lakes we
were on. The locals know them as Mink, where I was and Deer, where you
was. If they saw your plates or you mentioned internet, they played
dumb on you for sure because a week before some 'techno rave' happened
with over a thousand people from all over central North America at that
old airstrip. It was an internet link that brought everyone and the
locals are seriously pissed about it.
The one gent I was talking to that owned the dog implied 'he' didn't
play dumb on you because 'he' knows both names while giving someone else
there a dirty stare.....

Oh, so I ran into some 'local yokels' up there camping and for sure they
were the same ones with the ------- mouthy dog as when I/we were in the
bush and these fools were likely jerking your chain for directions.
A bunch of years ago the government changed the name of the lakes we
were on. The locals know them as Mink, where I was and Deer, where you
was. If they saw your plates or you mentioned internet, they played
dumb on you for sure because a week before some 'techno rave' happened
with over a thousand people from all over central North America at that
old airstrip. It was an internet link that brought everyone and the
locals are seriously pissed about it.
The one gent I was talking to that owned the dog implied 'he' didn't
play dumb on you because 'he' knows both names while giving someone else
there a dirty stare.....

Re: Flushing brake lines
I guess the particles in my system might be that then or worn off the cups
when my brakes were done about 2 months ago. The mechanic pushed back the
piston but when the caliper wouldn't fit over the rotor he forced them back
all the way by means of a huge pair of water pump pliers.
There isn't any oil in Ed's air filter just the gunk in the throttle body
around the choke plate just like we used to get back in the old carburetor
days.
I checked mine last evening and I had a lighter coating of gunk around the
choke plate that was also quickly cleaned with a dose of GumOut and the
attention of an old toothbrush.
On the Ed-mobile in the past couple weeks or so we have flushed the brakes,
cleaned the throttle body, replaced the air and oil filters, changed the
oil, replaced the CPS, and replaced the cap and rotor that was broken during
inspection.
I did not see the cap and rotor but Ed sent me an e-mail this morning
because I had mentioned the cap/rotor in an off-hand way last night.
"….and I was thinking about your question re how was my rotor
condition…..actually it was black even though I broke it in removing… As
important , although the cap was still usable, all contacts were
pitted/encrusted … so this may have contributed to the carbon situation in
throttle body…. see you…Ed"
The radiator is probably next on our hit parade.
