My 99 Lariat 4x4 has rear drum brakes, but I have seen some threads with 99 trucks having rear discs. Did some of them have rear discs and some have rear drums. What is up with this?

 

I have a 99 XLT 4x4 ORP with the rear disc brakes. I would assume that the discs are part of either the 4wheel ABS or some other package. I don't remember seeing it as an option. I just happy they are there. Hills around my neck of the woods and the pokie drivers make sure they get used a lot.
