i usually just run manual brakes on my mustangs but this one i didnt it has a brake booster

the car has been sitting for a few years just got it running i replaced both calipers all new brake lines new wheel cylinders and new master cylinder the brake pedal is sponge and goes to the floor and when you push the pedal it also changes idle when the car is off after its been running when you push the pedal it blows out steam threw the carb i am thinking its the booster some people told me it was master cylinder but i put a new one on it same thing booster is such a pain to change i am hoping it is something else


is there something i am missing
