I have never seen a 4.8/5.3 GMT900 pickup with factory brakes, and I believe that the options for four-wheel discs were tied to the 14-bolt in much the same way that the 4.8 mandates the 4L60E and the 6.2 mandates the 6L80E.

I meant factory disc brakes, lol. At least none from the factory. I've heard of guys swapping Tahoe brakes and I'm sure it would be a cakewalk to put the VortecMax or 6.2 brakes on.
