<VV> more brakes: question

To all:  Many are saying they have experienced "almost" no brakes with the 
dual MC when one pot is empty...  but shouldn't the pedal pump up at least a 
little?  My pedal did not pump up and I had no noticeable braking action 
from the pedal.  Perhaps if I pumped like a madman or held it to the floor I 
might have experienced a little drag, but I grabbed the parking brake and 
stopped the car instead which worked fine.  The brakes initially failed as I 
approaced a stop at a "T" intersection and I darn near hit a tree. 
Fortunately I wasn't going too fast and was able to steer through the turn 
missing the tree by about two feet, then stop the car afterward.  I can't 
express how upset I'd be if I had hit that tree right after spending money I 
really couldn't spare on a dual MC conversion.

If this is really all we can expect from a dual MC in the event of a failure 
I think we need a new brake conversion.  If this thing is not defective and 
that's the way it works I want my money back!

Tim,  Thanks for the compliment =)  It feels good to save cars from that 
kind of fate.

The brakes work fine on all four corners as long as there is fluid in both 
reservoirs, as soon as the front reservoir emptied out I lost ALL four 
brakes.  I fixed the leaking wheel cylinder, filled the MC and bled the 
system again and all four work fine again.  It works just like a single MC.. 
which is ridiculous!  I guess it's got to be faulty, but I'd like to test 
the new one when I install it.  I guess what I'll do is leave the chamber 
for the fronts empty on the new MC, bleed the rears and test the brakes 
before I fill and bleed the front brakes and see what I get.
