ok i have 56 belair running 350 and wot i believe is camaro diff with drum brakes. the front has been changed to disc with only a duel master cyl and proportion valve.No booster, now my dilema is two lines from master cyl go to valve and one out serves all the brakes?? so line out of valve goes to block for left disc then onto another block to right disc then same line to the rear. is that right??
