I was driving home from work through a residential district and was slowing to make turns, i experienced a horrible screeching noise that was coming from what sounded like the front driver side wheel area. it sounded like the screeching of metal on metal. i found a safe location and pulled off the road in a residential neighborhood. the issue occurred again while tow truck operator was driving the vehicle on the back of his flatbed and again appeared to correlate to use of the brake while driving it up the inclined flat-bed.
Abs pump failure. abs pump fails during an anti-lock event causing pedal to go to floor and no stopping power. occur sporadically when on ice/slush/snow or when braking on a rough rode.
