2008 Buick Enclave Question: What would cause the brakes to feel really soft and almost go to the floor?

On occasion, my brakes will get really soft and almost go to the floor when pushed. It will scare you to death. Then, all of the sudden, they are fine. Just every few weeks it will do this. I thought I was imagining this at first, but now my husband drove it and noticed it, as well.

    You might have the ABS system function, auto bleed, to make sure there is no air trapped in ABS controller. The TECH2 scan tool has this function.

    Many shops have them, I have one. It is the scan tools that the manufactuer uses for the GM line of vehicles.

    Do yo know a good mechanic in your zip code! If so, test drive is what it needs to determine the problem! Mechanic will know how to check for a master cylinder bypass problem by lightly and constantly applying brakes. Any warning lights on in dash?
