Can anyone come and help me with my power brake conversion? I installed the bracket, booster, then rebuilt the rear cylinders and replaced the fronts. Blew the front rubber hoses and replaced them. I had fluid between the mc and booster so I replaced the mc. I have gone through almost a gallon of fluid bleeding and still have no brakes. the rear reservoir bubbles when the peddle is released. I have no leaks. Is anyone able to come to Paso Robles, CA to edumacate me? Please?

sounds to me like you have a bad MC. You have no pressure, and bubbles. Hmm. Have you checked to see if your engine creates enough vaccume to pull the booster? Also, check to see if your pedal pushes the boosters rod deep enough into the MC. It may be too far, and you are damaging the MC
Also, you may have bad threads or a bad seal on the hard line connection to the MC. Not bad enough to drip or leak, but bad enough to allow air in. Try the ol'soapy water meathod. Spray some soapy water on the MC and its hard lines. Pump the brakes and have a friend look for any bubbles.

Well, I replaced the MC and found out I had to "bench bleed" it before mounting it. I did that and re-bled the system, adjusted the shoes, and "centered" the proportioning valve. Now the brakes work great. But, "the little light, it stays on."

I also used a dowel rod to measure and adjust the pushrod.
