Thankyou all for the brake help here with my 69, lesson learned.....

[tcs69rt]

I had the soft brakes, half a pedal issue. O'Reilly's was not happy with me, since I returned a few Master Cylinder's that leaked before and I understand from their point of view. I called them to see if they sold a pump to help get the air out of my lines. They wanted me to take it to people they knew at a garage. I did and the garage confirmed that their MC was bad. I was happy when the mechanic called them and said "Tim is correct, this MC is bad."

So, they sent a new one, I bench bled it and installed it under the eye of the mechanic, it was a good one. Then he got out the power brake bleeder and very little fluid would come out. I had a spare booster and we swapped it. Turns out a spring in the booster that activates the passenger side of the system was bad. I had a bad booster before but it put the pedal at the top and was rock hard to push. Lesson learned.....

Are you talking about the proportioning valve, the booster has nothing to do with the passenger side or driver side.
