Also, since I'm the one who started this thread, I guess I should give somewhat of an update.
I did this brake upgrade in February of 2017 on my 2001 Suburban, which is my daily driver. It's now seven years later, and I'm about due for new brake pads and rotors. I don't know the exact mileage, but I believe it's somewhere in the range of 50k-60k more miles I've put on my truck since 2017. I used all PowerStop brake parts except for the pads. I used Wagner Thermoquiet Ceramics as I've had good luck with those when I had the original stock calipers, and outstanding results with them on other vehicles. I used the PowerStop "kit" before on this truck, and my wife's previous vehicle and I didn't care for their pads. They wore out fairly quickly, and they made a shit-ton of brake dust on the wheels. Back to the parts I used, in addition to the Wagner Thermoquiet brake pads, I bought the PowerStop red powder coated calipers and brackets for a 2008 Suburban. I also ordered PowerStop drilled and slotted rotors for a 08 Suburban. I also replaced the brake hours while I was at it, but I ordered a set to fit my 2001, and they mated to the 08 calipers with no problem. Basically everything all went on without any problems. I also replaced/flushed all the brake fluid. I noticed an immediate improvement in stopping power when I was done with the brake upgrade. When I did a very quick stop, the tires would now screech on the pavement for a second or so. I've never had it lock up the brakes that hard prior to that day. Do I think it was well worth it, hell yes I do! And now it's time to order more 2008 pads and rotors for old reliable 2001 that I've owned for 19 years now.
