No, the master cylinder applies the brakes when you press the pedal. Two separate circuits, and when the seals fail in one it bottoms out and still works the other circuit. That is why the pedal goes further to apply the brakes. However, the corrosion that failed the first seal can also fail the second seal. Then you have no brakes.

The booster is for power assist, it is a separate component.
