Give me a brake

Checked the bleeders like you said today everything worked good.
A friend of mine said maybe what I needed was to put a adjustable perportional valve in line?.. To get more pressure to the rear and less to the front?.. It takes very little pressure on the pedal and the fronts hook up.The car didnt have power front disc brakes originaly someone had put them on two owners ago.
More ideas please....
