The sensor ring for abs (brakes) on right and left axels on the front of my 99 Mercury Mystique are both cracked causing abs to not function,also I just returned from getting resisters replaced for my blower motor which I just found out had a recall that was closed please let me know of anything I can do . I did have an accident I thought the brakes didnt work properly but dont know if it is related.
While applying the brake pedal went to the floor. Consumer was able to control the vehicle. Abs braking light appeared on the dashboard and remained on. Consumer drove the vehicle to dealer for inspection, and mechanic determined that brake pads and rotors needed to be replaced due to worn out parts.
Check engine light and abs light came on/off, and vehicle stopped in the middle of traffic.
