I am not getting any fluid to the rear brakes on my 69 mach 1 with front disc. Everything has is new or has been replaced with rebuilt parts. I just rebuilt the complete distribution and proportioning valve two days ago for the second time with no change. I have come to the conclusion that the little valve/spring inside the prop valve must be stuck, is this fair to assume? Thanks

Get someone to pump the brakes and hold the pedal down, then loosen the line under hood from the front reservoir line to the distribution block. It should squirt fluid when you open the line.

If yes. Then try the same on the line below the distribution block. If yes, then your blockage is further down the line somewhere.

Do the same with the rear reservoir .

I forgot to mention, I bought the centering pin so I know the pin in the dist block in in the right position
Did you replace the rubber hose from the body down to the rear end?

No I did not, the SS line is new, but the short rubber hose has been on there awhile.
