Reason I ask is because of the proportioning valve. Its the one item that you haven't stated you are using in the new setup that would have been in the old setup unless you removed it.
Without it the fluid and pressure gets split 50/50 between the front and rear calipers. Which would cause your issue.

I was wondering the same thing.
I have the same problem you describe John. Started when I removed the proportioning valve.
I've just lived without breaks for the most part
