Kind of a guess.Modern day systems have a proportioning valve mainly because of a disc/drum mixture.With the extra wheel cylinders in the rear,you might not be moving enough pressure/volume to the rear brakes.Certainly it is going to require more than the fronts.You might find that you need to get a adjustable proportioning valve to correct that.You have to be careful with them because the brake requirements do change when in a panic stop vs normal braking.
