The 2000+ Burbans do have brake upgrades. If you are willing to spend the dime, Stoptech makes larger brakes in the front and I think rear (disc brake conversion).

I've been trying to figure out if the 1992-1999 Burbans or my generation has anything, but I haven't seen it.

Here's a link to one site that has SToptechs.

Big brake kits usually do cost an arm and a leg. All I can say is, I do have a Stoptech kit on my Subaru, and it's amazing.

I did some digging and found out there is a company called SSBC that makes brake systems for the 92-99 Burbans.
