need help with ABS problem

I have a 2WD 2001 Ranger Edge. Replaced rotors, pads, wheel bearings and have the similar problem as others where the ABS is kicking in at low speed (and pulling slightly to the left when it has almost come to a stop). It will do this anywhere between 2-10 times and then the ABS light comes on. We pulled the computer code and it is reporting a bad Brake Pressure Switch. That's the cruise control deal that is covered by recall, so I popped a new one in there today (Motorcraft SW-6350) and it did not help. Same problem then the same error code. I think the ABS computer is fine - disconnecting either the left or right ABS sensors will throw the correct code - and swapping the left side sensor to the right side and vice versa make no difference. Still tries to kick in ABS at low speed.

What else can I try? We checked the sensors again, they are clean (no metal filings etc). The new hubs and rings look solid, clean and identical to what came off the truck. I'm guessing I have a bad hub, a bad ABS computer, or air in the system somewhere (in order of probability). Help!

The sensors are behind the wheel hubs on my 2001 Edge. You can see them (individually) by cranking the wheel all the way left or right. I'll probably replace mine. They are around $50 each at JCWhitney or on Amazon. Let me know if you solve your issue and I'll do the same.

I just solved this problem on my 2004 xlt. It was a bent tone ring on my new "quality" Wagner rotors. I pulled the side apart that was locking up at low speed and compared rings with my old rotors. The bent ring was plain as day. I was able to pry the ring off the rotor and straighten it. All is perfect now.

I flush the brake system everytime I change pads or shoes. All was normal with that.
