Cleaning calipers
Many of us with black wheels have this same issue. The stock Z51 pads would literally dust up the wheels driving around the block after thorough cleaning. Many have swapped out to less dusty pads, like the PowerStop pads, which do help. I can now go 500 miles with the PowerStops before a thorough cleaning is needed.
But even with those, the calipers will still dust up. Hit them with a soft narrow wheel brush when you wash the car.
Just as an added bonus, many of us are having pitting and peeling problems with the GM black painted wheels from the brake dust. I had to get my wheels powdercoated with 1500 miles. So far my calipers seem to be in ok shape. I am going to guess that GM used high temp caliper paint on the calipers. I do not believe GM calipers were powdercoated.
Oh, and just FYI - if you think the $300+ CarbonTech's will help, they will but they still dust a TON more than the PowerStops that are a third the cost.
Get rid of the stock pads!!!
BTW - Since the middle of 16 your Z51 black wheels are from China and before that Mexico. Next time you remove them check out the stamping.

The quality consistence of materials used to make some products and the product itself is easier to check and verify than others. With an item like brake pads, I'm less concerned if they are made in the USA. May not be an issue but a higher probability with US company concerns with liability etc. If GM sells it, they are liable. Not as clear cut with a distributor who can pass the liability to the manufacturer.
SIDE BAR: Validates my concerns about a critical product like brake pads. In my early former life I had managed an R&D group where we developed welding fluxes, etc. They use many oxides, mostly raw ores, and one was Bauxite. That is the ore that aluminum oxide and then aluminum are made from. All ores contain impurities, what we referred to as, "tramp" elements. Recall we could have purchased Chinese Bauxite but it contained impurities we could not tolerate when welding steel. We paid significantly more for Bauxite from Australia that had much lower impurities and you could believe their chemical checks, which we validated with our own measurements.
Another element used was sand, silicon dioxide. We bought that from an open pit mine in Ohio. It was near a drag strip I frequently visited when I lived there. You could see areas in the very large open pit mine that were pure white and most others that were the yellow/brown color typical of sand. They sold the white high purity product to electronic firms making chips. The brown was sold for concrete etc. They sold for far different prices so in the same mine you could get different levels of impurities! We bought low impurity product.
Manganese ore was the same. It came from Africa and fortunately we had a Division that made batteries. They use a lot of manganese oxides in dry cell batteries. Impurities create small cells that cause a reduction in shelf life. When they had a boat load with very low impurities, purchasing bought the whole boat for our Division, perhaps a 2 year supply-it was that critical!

Powerstop pads are shockingly inexpensive. I won't use them.

All the really good wheel cleaners used to come from Germany (as does Sonax), which has been the home of heavy dusting brake pads on German cars for years.
A positive, in addition to much less dust and the dust not pitting the wheels, is they stop better when cold! That is my observation supported by Carbotech info. After entering a 4 lane divided highway from my street with traffic traveling 65 mph I have to make a turn in 100 yards. I can enter traffic and with cold pads they stop on a dime! I usually have to stop quickly and make a turn onto the little used 1/4 mile long road between farm fields-fun turn! They are also very linear and I have had zero noise in over 2 years (I problem I had with the OEM Z51 pads until I beded them.)

If you have not touched them in 650 miles, that's way too long. They should be cleaned every couple weeks at a minimum. You need to stay on top of them so you don't have a mess when you do clean them. Same idea with the carbon on the exhaust tips.
I do the same thing and it makes it pretty easy to keep the calipers and exhaust tips looking great.
