This is correct, there is a big black drum (Vacuum) with a servo (fluid)
attached
to it. There are brake lines that run from the M/C to these servos (fluid) and
these servos are attached to the black drum. When I pulled the old drum/servo
units off, I of course disconnected the vacuum lines that run from the black
drum
to the manifold and when I did that a brackish fluid came out of the fitting on
the black drum.
Also, I am confused about weather any fluid should be coming from the black
drum
and the vacuum lines. I also get a white smoke from the exhaust after using the
brakes.
I think, but don't know for sure that there should be nothing but air in the
black
drum along with the diaphragm. I also do not understand how the black drum and
its inner workings function.
I am hoping someone can enlighten me. What I think is that there is a large
diaphragm in the black drum that some how helps push the brake fluid out to the
wheel cylinder via a five way switch. I assume it is to increase braking and to
make it easier on the driver,
Sorry if I have gotten long winded and bombed the list with a tedious question.
THANKS!
