My 2004 Sport Trac suddenly developed a braking problem...at 35000 miles. While applying brake pedal, brakes would pulsate frantically. Would NOT stop !..I would press the pedal even harder but the truck would go right through the red light or stop sign !! Scary..I was lucky! I'm an ASE master Tech spent 35 years repairing autos...snapped my lower back, needed several operations...don't work now. I knew this was an ABS problem, but could not get into it myself. I brought it to a "decent" brake shop...to have the brakes looked at. I looked at the pads and rotors....pretty bad..one rear caliper was frozen. I figured that was the problem with the ABS. I had them replace all new rotors, pads, tires,(they were very noisey shifted belt in one)....and replaced the rear caliper. Got the truck back.,HUGE bill..SAME PROBLEM..I pulled over and disconnected the ABS harness from the module,control,brain..or whatever they call it now. I had brakes...could stop...so I drove home....after bleeding the rear brakes myself, with a bleeder check valve in a bottle, I re-connected the ABS system. Took it for a ride...went right through the stop sign again !! Pulled over, disconnected the ABS again....drove...had brakes...Crappy, but it stopped when I wanted it to.I feel it is a speed sensor...do not have a tester, or even a book on the system. Can't afford to take it to the dealer, or any other shop....so I drive with the ABS light on. I have to be very careful in snow. Truck only has 45000 miles !...Thanks.
