Brake Abs Warning Light problems of the 2005 Mazda Tribute

I have a 2005 Tribute purchased in Aug of 05 with 26500 miles. My abs light came on while backing down my driveway and the pedal went to the floor and rebounded with force. Then I had no brakes. Stopped the car with the emergency brake. Mazda needs to get this fixed.

2005 Mazda Tribute - 21,500k miles. For the third time since taking ownership in August 2005, the abs and 4wd lights go off whenever there is heavy rains or snow. First dealer service diagnosed as real wheel turning out of sync with other wheels; second diagnosis was the need to add grease somewhere; third time happened after dealership hours and next morning lights flashed again at startup but turned off.
