HELP!! Brakes went out!!

[stanglifemike]

The pedal is just going to the floor now. I've always had pump it some, and some times at a redlight, the pedal would go to the floor after a minute or so, and I would have to repress the brake pedal and all was well. Yeterday though, on the way home I had nothing. I was near the neighborhood so I was able to get it home and into the backyard. I pulled the front wheels and loosened the line at the caliper. I had my daughter push the brake pedal and fluid was coming out just like it should. So, do you think its my calipers? What are the chances of both front calipers going out at the same time though?? Could it be the booster? Please help, and thanks for any thoughts
