ABS right before car stops

[79broncojosh]

Well it seems the more I fix the more goes wrong!
My truck started this this morning, When I come to a stop at a light or something the ABS pulsates right before the the truck actually comes to a stop, anybody know what is causing this?

I've had this twice (both front wheels). Highly likley that one of the ABS sensors has gone bad.

On one of mine a good clean up of the toothed ring sorted it. You need to use a small flat bladed screwdriver to clear out the crap between the teeth The trick is working out which side is causing the problem.

If memory serves me right, the sensor has a resistance of about 400 Ohms, but as this is an inductive sensor this will only test to see if the coil is faulty.

I had this happen when the wheel bearing had gone bad and was shooting shrapnel at the ABS sensor
