[T2] Vacuum assist

[Paul]

I believe if the check valve is bad or installs backwards that would result in a loss of vacuum or no vacuum assist.  Sounds like you still have air in the system and is more noticeable when vacuum assist is applied.   Brakes are tricky and air likes to hide unfortunately.

As soon as I start the engine, the pedal goes to the floor. Is the vacuum assist causing this? How do I fix it?
