replace the MC. Thats your problem.
if it was the booster, there would be no change when the car is on because there would be no vacuum and it would be as if the car was off.
I'm guessing no ABS right? cause that makes it a bit more complicated.
Unless you can see brake fluid shooting out from the lines (check every inch for leaks while someone pushes the pedal) or fluid shooting out from the calipers, it's the MC.
I've had mc's that were fine one day and then boom, they blow a seal and no good.
NEVER assume a part is good EVER, I don't care whether it came off a working car, or is brand new out of the box. ALWAYS check everything.
change the mc
