2007 EXL Brake Pedal goes to floor
 

I have a 2007 Odyssey Touring model. The brake pedal has a really soft feel to it. If held down firmly it slowly goes to the floor board in about six seconds. The dealer has replaced the ABS modulator with no change. I returned it and they rebled the brakes several times. The sevice manager told me that all Honda have a soft brake. It still goes to the floor. Anyone have an alternate idea? If it was my old Ford, I'd say the master cylinder is bad. Thanks.
More...July 31. Dealer replaced master cylinder and it still does the same thing. Braking action is somewhat better, but the pedal is still mushy and I can get the brake pedal to the floor in a short time.
