ABS problem with 2000 Explorer

I am having an issues with the ABS system in my 2000 Explorer. When I am coming to a stop (not always a complete stop, it aslo happend in stop and go traffic) the ABS system kicks into action (usually around 5 to 8 mph) and will not let me stop normally. It happens on dry and clean pavement so it has nothing to do with road conditions. The ABS warning light does not come on and I have no trouble codes when I hook it up to a scanner. The one thing I did find when driving with the scanner hooked up was that the rear ABS sensor kicks in first and the front sensors don't turn on until about 5 mph. Also, with the scanner hooked up, the ABS problem doesn't happen and work as designed. I have since taken out the ABS fuse from the fuse box under the hood. Since I have done this, my first application of the brake I run into the same problem and then the ABS light comes on and my brakes work fine in manual mode. Has anyone run into this problem and if so what are the steps you took to fix it.

I have this exact same problem. Don't have a clue how to fix. A couple shops I've taken it to said their really not sure and it would take some time ($$$) to properly diagnose. Since your original post was kind of old I figured I'd reply back to see if you ever got it taken care of. Maybe some others are experiencing the same symptoms?

I've heard of this a few times. It is most likely your wheel mounted speed sensors, they either will need to be cleaned/replaced, because they aren't picking up the rotation of the wheel, so the vehicle thinks it is in full lockup.

I just wanted to send a follow-up to my original post as I am still stumped. I replaced the rear wheel speed sensor because it was only $15.00. That didn't help. I took the time to pull both of the front wheel wheel sensors. I cleaned them and also checked for vehicle reference voltage and resistance. Both checked out. These sensor's are $150 a pop so I don't want to replace them if I'm not 100% sure that is the problem. Does anyone have any other ideas?

I have a '97 ford explorer that does that too. When I slow down, almost to a stop, my ABS system kick in on any kind of surface (even bone dry). I just live with it cause I don't really know what to do or whats wrong with it either. What I have done, is, when I slow down to stop, and it kicks in, I quickly release and re-apply the brakes and it seems to stop (if its safe to do so, of course).

I drive an '05 Explorer and the same exact thing is happening to me. I actually tore into it a bit yesterday - thinking the sensors needed cleaning (like one other post recommended). As theses things appear to be sealed in the wheel baring housing, I didn't take it that far. Instead I just cleaned the electrical connections. Anyway, I tested it today and the same thing is happening. I'd like some help or direction if anyone has any advice.
