Pulsating ABS brakes on 1996 explorer

[karlmueller]

When I am coming to a stop, on dry roads, my ABS brakes will pulsate just before the car stops. Any idea of why and how to fix?

You probably have a faulty wheel sensor, that is falsely reporting a locking wheel as you come to a stop. You will need a scan tool or labscope to find the bad one. AutoZone may be able to help with the scan tool. View the sensor inputs with the scan tool while you drive at low speeds. You should find that one sensor stops sending consistent data when you speed drops below 5-10 mph.

Thanks for the input on the pulsating brakes. Any idea how difficult it is to replace the sensors? Or can they be repaired? Thanks again.

The front wheel sensors are in the front hub/bearing assemblies. To get to them, remove the brake caliper, rotor, and dust shield. The rear sensor is bolted into the top of the differential housing. That one is the easiest to get to, except that you need to be under the truck to get to it.

Do you feel the pulsing in the vehicle or in your foot on the brake pedal?
