Subject:Potential bad Brake Master Cylinder?
From:craig cowan

So i just put on a brand new FTE brand brake master cylinder, 'bench bled'
it, opened up all my bleeders untill i had a good flow of fluid coming
through, and then i started my engine to see what would happen.....
And SMOKE! I had a nice cloud of smoke coming out of my engine and thought
"Wait, the only thing i've done since parking this a few days ago was work
on the brakes...."
Well one thing led to another and i pulled the vaccuum line that goes from
the brake booster to the intake manifold, plugged the hole in the intake
manifold (Mercedes Benz Wheel Lugs work perfect for this!), and started the
engine. I ran it untill it no longer smoked then shut it down. I plugged the
brake booster line back in, and started it back up. Surely enough, after a
bit, SMOKE. So i'm burning brake fluid.
I assume this to be REALLY bad for my engine, but can't be sure that if it
was just some spilled fluid in the line, that it hasn't been fully burnt
yet. I haven't ran it long enough to see if it effects fluid level, but it
smokes alot.
I haven't really checked the pedal yet to see if that feels bad, i just
assumed it needs a good proper bleeding...... But that's no good if the
master's a dud.

What do you guys think?
