Steve,

Since in your original post you stated that the rear brakes work, then you 
might try swapping the front brake circuit line with the port on the MC for 
the rear brake circuit.  If it works then I think that's strong evidence 
that the MC is bad.  I apologize if you have already done this or someone 
else suggested it.

Good Luck
