What follows is generic brake advice not specific to the Unique brand. If the balance bar was set wrong but the rest was right, the only effect would be to have either the front or rear lock up too soon. If neither lock up, I'd suspect:
1. Air in the lines.
2. The master cylinders are not sized right for the calipers (e.g., you run out of MC throw before the calipers are sufficiently extended).
3. A rubber flex line is expanding under pressure.
