Hydroboost swap? Cheap and effective.

GM had a bunch of issues with drums on the older 800 trucks. They went back to drums in '05, and haven't had any issues since. They work, require less maintenance, and are less expensive.

If you're not doing 100mph+ runs on the freeway with heavy braking, the stock brakes are fine. I do prefer pads that are a bit more agressive, however. Also, you won't gain anything by installing stock replacement slotted/drilled rotors on the front. They just reduce pad contact area.
I will disagree. My '09 5.3 truck with drums in the rear always had a "soft" pedal feel I found lacking. When I took my '11 6.2 w/ the 14-Bolt rear and disc brakes on a test drive when I was buying it the FIRST thing I noticed was the brake pedal feel and how much better it stopped.

mine are stock replacement rotors, and the braking is a ton better than a stock rotor. ive had plenty of 110mph to 10mph slow downs at the track with these things. no warping or anything and i have 10k on them *abusive 10k at that* my stock rotors showed signed of warp within 8k and was complete crap!

Yeah 91Z28, same here.

OP, why did you get a $35k truck with drum brakes if you wanted discs? I've got a 2011 with four-wheel discs, and it didn't cost more than $35k.

My brakes are WAY better than any GMT800 I have ever driven.

I posted a parts list for the hydroboost conversion. Just waiting for somebody to man up and try it.

GM went back to drums on the rear due to:
-more surface area v. disks (a.k.a they work better)
-better durability v. disks (gmt800's had numerous rear disk issues)
