I did a little research on it though, and looked at it - it's not physically hard to replace at all. It's easy to get to and it's just a matter of lines, nuts, and bolts.
HOWEVER - during my research I learned that it is CRUCIAL to follow a strict procedure for bleeding the brake system afterwards that involves bleeding the valve and master cylinder as well as doing different wheels it certain times. If not done right it will cause all sorts of problems. I guess that he did mine right, and I do recall him saying something about the bleeding to that effect, since it fixed them up perfectly and I have never had any problems since and it's about three years now. The ABS light comes on when I start the truck, does it's self-test of the system, and goes off like it is supposed to. It has never come on at any other time since. Ditto for the red brake light, the only time I see it is when I put the E-brake on.
And the RABS works like new now, for whatever that is worth.

They are dry as can be. It is odd that both are grabbing, that is why I think it could be the valve.

couldn't resist. I too have had problems with my brake system. Once I have the chance to put my Bronco up on stands again, I'll have to do a lot of R&D on my system. Especially since I swapped out the rear drums for Rotors. Which I may at some point swap out them for something from like an Expedition.

I finaly got the ABS valve in! It worked, that was my problem. They actually work better then they did before they were locking up. The seal around the electrical on the old one leaked and allowed brake fluid into the wires. Thanks for the help!
