Brake booster

Brake booster
I just had my brake booster rebuilt on my 57 olds and bled the system and bench bled the booster and adjusted the brakes. When I first step on the pedal it goes to the floor and then after 1 pump it is perfect, any ideas why it is doing that?

No air or vapor can escape from a closed system. Even if you can get the bubbles to dissolve in the fluid as soon as the pressure is released and the brakes heat up the fluid, those air or vapor bubbles will be right back again.
