2003 Ford F-150 ABS Problem with 57,000 miles
v8 5.4 Automatic 4 Wheel Drive

When braking my 2003 F150 (57,000 miles), just before coming to a complete stop (slow speeds)the ABS engages / activates & the brake pedal goes to the floor. This happens every time when the vehicle comes to a normal stop. There are new rotors / pads on all wheels. There are no trouble / warning lights being displayed. The ABS sensor wires look in-tacked when visually checked, any ideas?

This will happen when one sensor is not reading corect. If you have a scaner graff all 3 speed sensore and look fore the one that looks out of place. Then check the toner wheel. Might have cracked or (loose. Un even air gaps will also do this. Check it out and let me know what you find.

All 3 speed sensores & toner wheels check out ok (did replace dvr front though, since it broke when being removed) problem still exists. ABS kicks in only when coming to a stop (when slowing between 5 & 10 mph). Any other suggestions?
