1997 F250 ,Rear anti-lock or 4 wheel anti-lock?

I am replacing the front rotors and pads. I am buying the parts and paying someone to change them. I went to the parts store and they said that my model has both a 4-wheel and a rear-wheel anti-lock brakes option.
On one occasion, I slammed on the brakes and felt the backs lock up and then release. I assume I have rear only.

The parts store told me that there would be teeth on the back of the rotor, but I don't want to take it off to check unless I absolutely have to. Is there something in the VIN, on the engine compartment, sticker on the door that will help me?

I bought the rotors for rear-wheel anti-lock and if it indeed has 4-wheel, I return them and pay the difference.

I have a 1997, F250 Crewcab, 2WD, Powerstoke, XLT.

Can anyone help me?

You haven't any anti lock at all, what we have is a Rab's valve..in a panic stop all it does is just as you get close to stopping it will dump the pressure to the rear brakes causing the truck to jump forward..F*** ford idiot engineers

I assume I have RABS, is there anywhere I can confirm that is what I have on my truck, as opposed to 4-wheel ABS?

yes you can on the frame rail under the drivers side floor board there is a valve bolted to the frame with brake lines going in and out. If you had four wheel abs there would be a wire in the front following the brake hose down to behind the front rotor . Hope this helps

If I remember the only OBS units that had 4 wheel ABS were broncos. Everything else was rear antilock.

Sorry, I just misread that and thought I would have a little fun.

You sir are correct. Every OBS Ford I have had, or been around has been RABS

I've driven countless Fords with rear antilock with no problems. There might be some problem with the module or the valve on your truck which the self test isn't detecting.

The ABS light on the dash has been on since before I bought my truck. She'll lock right up, but my first rig was a 69 Scout with manual drum brakes all around. Not having ABS is no big loss to me. I just need to unhook that light, or put a piece of electrical tape over it.
