68' DART BRAKE WOES

mydart270 said
Thought I was home free with new brake m/c on all wheels, new brake pads front and rear, rebuilt power booster from KARPs, reset power brake push rod to spec per FSB, bleed brakes, nice and firm pedal, stated car and WOW....pedal goes to floor. What is going on, wifey says "sell it".

Original brake pedal rod in use, do I need a special one for the power booster from the pedal? 9 in drum brakes on all 4 wheels, 1 in bore rebuilt M/C and no air bubbles when bench bleed. M/C totally filled, engine is OFF and slow pedal push and geyser with "air bubbles" (i don't think this is right!) in M/C front and rear reservoirs....dah!!!!!.

Need some help. Where do I start?

Thx MOPAR geeks. UR the best.

After many failed attempts to bench bleed my MC, I dropped that idea years ago. I now mount the MC in the car and install some fittings I made that screw into the ports with clear tubes that go into the MC reservoirs. With the help of someone else, I ensure the reservoirs are filled with fluid and the tubes are immersed. I then very slowly pump the brake pedal to expel the air. This takes some time and patience but has worked on many I've done. I had one new MC from NAPA once that I never could get bled. They exchanged it and the other one worked as expected.
