Hello all. 68 coronet 500 was a power drum car that I am converting to a power disc front car drum rear. I have everything installed but I still can’t get this thing to stop or get a higher brake pedal. Right stiff disc brake kit using my pier drum 8 inch booster with a 73 duster proportioning valve that mount up to the factory lines from my power drum setup. New wheel cylinders new lines everything new but the booster. I have peer bled the system and did the old brake pedal pump up and hold method. I don’t see on air bubbles. Calipers bleeders are on top and rear brakes adjusted up. I am lost. Next I was told to adjust the booster to master cylinder rod but how far off could it be ? My pedal is just above the floor I can’t see a 1/8”of an inch making that big of a difference? I was told tge proportioning valve was a bolt in replacement for the distribution block. All the lines went right in thx for reading this. Help please also I only used the valve not the added brass port in the picture.
