[V8] Still frustrated, have to rant.

If you're sure that you measured correctly, then you may only need to adjust
the brake light switch at the pedal arm.  

The BRAKE light comes on for a couple of reasons one of which is bomb
pressure.  If you've had the system apart, make sure the "power system"
hydraulics are bled completely and the brake bomb has built up significant
pressure.  It might even be worthwhile to do the procedure where the front
wheels are in the air and you turn lock to lock to get any air out of the
hydraulic pressure system.

I don't think there's any ability of the system to sense air in the brake
lines themselves.

I finally got the replacement servo in the car and the brakes still don't
work.  In fact it's even worse now.  I no longer get the initial grab if I
stab hard on the brake.  Instead it just goes right to the floor and I
barely have any brakes at all.  At least before I could still drive the car
if needed.

Also, not only does the "BRAKE" light stay on, but also the actual brake
lights on the tail of the vehicle stay on.  I'm pretty sure the reason the
taillights stay on is that even though I measured it carefully, I must have
gotten the adjustment for the clevis incorrect so the pedal isn't coming
back up far enough to hit the switch to turn off the lights.  The problem is
that I'm not sure how to re-measure it without completely removing the servo
again.  The clevis can be adjusted without removing the servo, but I can't
measure the correct distance (230mm or 9") from the base of the servo to the
hole in the clevis, because the firewall is now in the way.  Should I just
adjust it far enough that it engages the switch?  The service manual made it
look like it has to be pretty exact.

As far as the "BRAKE" light, will it stay on if there is air in the lines? I
know I lost some fluid when I removed the lines so I'm sure I have to bleed
the system, but it's worse than it I expected.

What's worse is that, in addition to everything else, I'm now pretty sure
the rear calipers are not disengaging entirely so I also have THAT to deal
with.

Anyway, as always I'm open to any input, suggestions, derision, etc.
