resevioir stays full but brake pedal drops to floor. Brakes will grab, but only very lightly. Pedal is not soft - it just goes to floor. No apparent leaks anywhere. This happened all of a sudden, one day the brakes were fine, the next day they were terrible.

If you have no leaks at the calipers, hard lines, flex hoses and rear wheel cylinders, then it is most likely the master cylinder has an internal leak caused by a bad seal and would have to be replaced.
