Prowler , did you bench bleed the MC before you installed it ? A quick check on the proportioning valve is to do a few stops from 35mph and carefully check the rotors for heat soak . If the fronts are equally hot and the rears are barely warm then thats your answer , Prop valve NFG . Conversely if one rotor is considerably hotter on either the front or the rear, than the other it would appear that you have a seized piston in the that caliper . Good Luck Steve.
