Brake Pedal Goes to Floor When Car is Running

If I'm rading this right, when you start the car the pedal goes to the floor without you even pressing on it? If so, defective brake booster is my diagnoses.

OH!
Thats possible.
If that is the case then it is the booster for sure.
I had a Lincoln that did that.

I just re read his post and I think you are right Matt.

Yup, booster for sure.
