[xj] Brake M/C Work/bench bleeding

“Doug Dwyer” <@Doug_Dwyer>

Charlie,

Your description of the process is “spot on” except the XJ6 master
cylinder…unlike most “Amuricun” cars… does not have “bleed fittings”
to attach any tubing onto. ! I was faced with this dilemma a couple weeks
ago when I replaced the M/C on my '87.

Ideally one would have…sitting in their ubiquitous “junk drawer”…
some nipple fittings to fit a XJ6 M/C. As luck would have it, my junk
drawer had no such fittings.

I resorted to a far messier and less effective method. Fill the M/C. Firmly
press two fingers over the vacant fitting holes. Slowly pump the M/C plunger
(using junk drawer screwdriver) until pressure is felt. Hold pressure with
the screw-pusher, release fingers, get sprayed with brake fluid, re-set
fingers, release plunger, repeat a few times, clean mess. Eye protection
recommended !

Well, it did expel "most " of the air from the cylinder. Hardly the
preferred method, but necessity is the mother of invention.

BTW, James, I would suggest flushing the system with 64 ounces (or 2 quarts,
or 4 pints. Ask Charlie.) of brake fluid. This will clean out some of the
old, miserable fluid currectly residing in the plumbing. If yours is
anything like mine was, it’ll really need it ! When you do your
wheel-by-wheel bleed, just keep doing it till you’ve run a pint (or 16
ounces) thru each caliper.

Attach a bit of tubing to the two connections on the side of the M/C,
and rout this into the reservoir.

Doug, Doug, Doug…I knew that…8^)

Gotta leave something for someone else, to comment on…

Actually, I too, have to get the reducers to fit as you said.
