2019+ Silverado brake upgrade?
View attachment 5533
I did the first (after originals), front pads on my 1999 Silverado at around 120k using dealership pads.
Second set of AAP's highest line around 225k. Those dusted badly but otherwise seemed fine.
I replaced the rear pads around 230k, I think with something from Oreilleys.
Did the 2019 front brake upgrade around 270k. Very nice stopping power improvement

283k currently.
Edit: You have to run larger rims for the 2019 front brake upgrade, so that may be a deal breaker for you.
I replaced the rear rotors/pad on my 06 Suburban 2500 with some Powerstops a few months ago and I have been pretty happy with them.
