I didn't realize that there was a different master cylinder for power brakes. I bought the one I have on the car before I thought about adding the power assist. Sounds like its worth a try. Think I have a original 70 master cylinder in the shed. Maybe I will try my hand at a rebuild.

Even though it is new, it could be. Or maybe you need to adjust the plunger/pedal? It has been way too long for me, but I had the opposite problem of the brakes applying themselves after a while until the wheels locked. That was from the adjustement bein off the other direction. Too tight and the brakes are always on! Maybe too loose and you get lots of travel and no pressure. Is the master the right one for the other parts? You say you might put the booster back on the firewall, so does this mean the master is a non-power master? I'm not sure what would happen if you had a power master with no booster, but I think it would be a problem to add a booster to a manual master cylinder. If things are mismatched here, maybe that is why you get no power from your braking?

Car looks and runs great but won't stop. I have absolutely NO pedal. Its not spongy but way to much pedal travel. Hopefully someone out there can guide me to a solution. Here is what i am running... 4 Wheel Drum Brakes - All pads and hardware are brand new 4 New Brake Cylinders New Drum Brake Master Cylinder Used GM Power Booster Original Proportioning Valve All New Lines Silicone Brake Fluid I adjusted all of the brakes but it did not help. Bled them again but did not find any air in the lines. Wondering if I should ditch the booster and put the master cylinder back on the firewall as it was before. It is the only thing that I changed in the setup. Any help would be greatly appreciated. Now that I have it done I want to drive! Thanks, Dan
