    If it were a vacuum leak, the pedal wouldn't sink. It seems more like you're losing pressure in your brake system somewhere. Does it sometimes seem to depress rather much without having any effect on the car's momentum?

        If you're not losing brake fluid, it's probably your master cylinder.
        I don't think a bad break booster would cause the pedal to sink to the floor.

                Pretty sure luke was saying you spelled brake wrong. It's brake. The e goes at the end.

                your problem is Not your brake booster from the limited info you gave. A problem with the booster would make it very Hard to press, not easier.
