Hello Everyone. I recently had my oval type power brake booster rebuilt on my '61. When I start the car with my foot on the pedal the pedal goes way from my foot, but the pedal doesn't come back up! I have to release the vacuum from the hose at the booster to get the pedal back up. If I cap off the vacuum hose the brakes release, but of course there is no power system. Could it be something wrong with the trigger arm? I have bled the brakes and adjusted the master cylinder rod, but have not attempted to play around with the trigger arm yet. Any info greatly appreciated. Thanks ahead of time. Nick Nichols
