Driving my car one day and everything is fine, I park and let it sit for 2 days before driving again. But this time when I start the engine and try to shift to drive my break pedal goes all the way to the floor I can't figure out what is wrong. I checked for leaks, found none I added break fluid and still they don't work, what else could it be?

    Internal leaking of the master cylinder. How empty was the reservoir , that you needed to add brake fluid?

    It was low, does this mean I have to replace the master cylinder ?

    NO , at this point , it should be properly diagnosed by a qualified person(s), you may have problems elsewhere in the system.
