Haven't had a street rod in years. Bought a 1940 ford sedan (not a show car) that had disc/drum, under the floorboard with remote booster. Put disc on rear, new master cylinder and new proportioning valve. I cannot get the brakes to bleed and the pedal goes to the floor. It appears that all of the air is out of the system but still not a good pedal. Cannot put mc/booster together because of the way they are mounted (IE remote booster). Put on direction disc valves. Any help would be appreciated.
