Abs system activates prematurly causing ABS motor engagement. This leads to brake pedal pulsations and consequently complete pedal excursion. The vehicle at this point reacts as if it will not stop! There are no warning indications when the incident occurs nor are thare any hard or soft codes set stored in the computer. The vehicle returns to normal stopping operation untill this bazar occurance happens again. It is highly intermittant and seems to follow a temperature relationship. The longer the vehicle is driven,the frequency of events increases.when this happens,it leads one to believe that the vehicle will "not stop" because stopping distance increases dramatically. This does not have anything to do with an ABS recall that has been performed effectly by my dealer. The problem existed prior to the manufacturers recall and continues to exist today. I fear that this will have severe consequences and will ultimately lead to catastrophic brake failure. All brake related hardware and peripherals check out fine as per my expert techmicians. My conclusion is that the ABS hydralic control is faulty in my vehicle and many others. Please help as I would not want to see this turn into a firestone/ford disaster.
