Brake Antilock Wheel Speed Sensor problems of the 2001 Ford Windstar

My 2001 Ford Windstar's brakes were locked and I could not disengage them. I had the car serviced for this problem many times, most recently in January of 2010 when I was told that they determined that the problem was the rear speed sensor. They replaced it and told me it was all set and wouldn't happen again. Yesterday (4/6/2010) while I was travelling in interstate 95 south it happened again with disastrous consequences. I put my brakes on to slow down but instead of slowing down my car came to a screeching halt in the left lane of fast moving traffic. We were hit twice and the car was totaled along with the other cars involved. I am wondering if this has happened with other 2001 Ford Windstars.

Braking distance suddenly increased even after the latest recall, my car abs light continues to stay on. I have had the speed sensor replaced and the wheel sensor cleaned at the dealership yet problem persists.

The contact owns a 2001 Ford Windstar. While driving various speeds, the traction control, abs, and service warning indicators illuminated on the instrument panel. The traction and abs became inoperative. The dealer inspected the vehicle and stated that water entered the computer module and they reset the codes. Immediately after the repair, the failure recurred. He took the vehicle to the dealer again and had the front wheel speed sensor replaced. After the repair, the failure codes appeared again and the vehicle was taken back to the dealer. The technician replaced the abs power relay. The contact took the vehicle to the dealer again in reference to the failure and they stated that he needed to repair the abs module at the cost of $800. The vehicle has not been repaired again. The failure mileage was 115,000 and current mileage was 119,000.
