Hello - Still working on my '58 Spartan 80. I thought I did everything the right way, but '0' brake pedal. The original master cylinder was rebored, sleeved and rebuilt w/ all new parts. Instead of the original AOHC system, I replaced the power boosting system with a c. 1970 remote Bendix unit which has been professionally rebuilt. Wheel cylinders (2 @ ea. wheel) all new, and I hooked up just one rear corner, plugging the 'T' connections, to test the system. Bled the system 4-5 times consecutively, ending with no air bubbles whatsoever, and still nothing....pedal all the way to the floor, easily by hand, even with all bleeders tightly closed and no external leaks whatsoever - and will not build pressure, even when trying to 'pump' it up. I'm thinking 'hidden' air pocket; improper rebuild of either master cyl. or booster, causing internal hydraulic 'blowby'; or possibly hydraulic 'engineering' problem(?)by using 3rd generation vacuum booster with old type master cylinder. I know the later boosters have smaller diam. but longer power cylinders than the hydrovac type, but both supported same size dual wheel cylinder systems, so I can't see why that would make a difference. If anyone has been at this point and figured out the problem, I would sure appreciate your guidance. Thanks!
