Force of habit with me, is to visually check the brakes with rotation of the tires. At least with that schedule, it helps me keep the brakes and other components on a regular maintenance check. Don't use the monitor.
I bought my truck pre-owned, which had some performance parts already installed, with one being GM's front "Brembo" brake option. I mention that, because that option has the sensor disconnected, so the monitor is of little use anyways, when it's just the rears.
Last year when looking for those front pad replacements, I decided to replace the rear pads at the same time to pair with the fronts. Sort of a baseline of reference for me for maintenance. Anyways, I ended up staying with the ceramics, deciding the carbon-fiber ceramic pad wouldn't get up to temp to be an effective alternative, even if I had been buying for the front OE and considering my at times, spirited driving. I only see that choice for race, track or police package, imo.
On a side note, looking at SS braided hoses to get that pedal feel I had with my previous truck.
My choices of brands are from a checklist of what I'm looking for in pad construction and components that I've used in the past and while Wagner would have been to look at, it seems the Wagner (with a few other brands) line of pads have suffered in quality and performance lately. Something to look at and consider also.
