Dartin for Divorce

Bled them again, did the syringe through MC ( 3 full syringes through the rear port for each side) for the rears and then gravity bled the fronts style absolutely no air bubbles in the fronts and dang they still dont feel right. first pump of the brakes is still way lighter than the rears, I dont see any leaks so now I'm starting to get frustrated. I used almost a full bottle of brake fluid this time. I have no clue what I should do. Maybe its the prop valve? Or maybe I'm going to have to solicit my wife to pump the rears a whole bunch for me. Idk
