Parts stores love to sell drilled/grooved/slotted rotors. USUALLY they're the same junk Communist Chinese rotors sold in the "discount" line, but someone threw them on a mill, and then stuffed them into a fancy box; the resulting profit-margin enhancement can be substantial.
First Guess: Less a matter of the rotors, and more a matter of fresh/better pads.
Discount pads tend to wear rapidly. I paid for "premium ceramic" pads once; couldn't wait to get rid of them. Didn't stop well at all. Wore like iron, I was stuck with them for a decade.
There's a hundred pad formulations; every brand claims to be "the best". Good luck, I don't have a solid answer except to say that I'm satisfied with plain ol' semi-metallic from the moderate-upper end of the price spectrum.
Don't know about your K2500, but my K1500 uses leading/trailing shoes at the rear; I just hate 'em. I believe it's a poor design. I'd much prefer self-energizing shoes with the adjuster link at the bottom, like older vehicles.

My first point was more of a question as to if these parts are know to fail or give issues and if they do are they something that you could get a repair kit for or have to buy it fully assembled
As for the drilled and grooved rotors, yes I see where you are coming from but I was shocked at how poor the brakes felt that I needed to try something, the pads I have been using are probably at the cheaper end of the scale as all the ceramic pads stated that they were not recommended if towing trailers, which I do a fair bit of. I don't know if this is right or wrong so cheap pads have been the order of the day and I do get through a set in about 15000 miles or so.
I don't know what my rear shoes are other than huge, think about 3" wide set up from memory but the last time I looked at them was 8 years ago when I first got the truck. I would suspect that they are leading/trailing as on yor one. I know there is still life in them as there is no squealing or grinding, the test shows them working well via foot brake and the parking brake works really well on hills etc. Maybe I will take a look just to be certain but leaving the occassional foot to the floor issues the foot pedal is firm and does not drop much when pushed before the truck starts to slow, it is just that it never seems to slow "quickly" if you get my meaning and you can often think that you are not going to stop in time (a little like brake fade)
