I got my Bendix Treadle Vac brake booster back last week and installed it. I can say that Harmon really did a great job restoring this thing. It looks brand new and what’s really interesting is they sent back all the parts they replaced and clearly, this pump could never have operated with the old parts…they were corroded, dried up and simply covered in old fluid muck.  After installing, I used a Harbor Freight one man brake bleeder and it worked just fine. At first, it seemed to take forever before I saw fluid coming from the reservoir but it finally did. It passed bubbles to the furthest cylinder (right rear) for such a long time, I thought there must be a leak. Just before I considered aborting, the line cleared up and I moved on to the next. It took a long time to bleed the breaks, but once it was done, I felt confident all would go well. I cranked the car up and pumped the brake pedal a few times and it was evident the brakes would work, and they did. So, glad that job is done.
