I had NAPA Ultra-Premium Polymer Coated discs with NAPA Gold Premium ceramic pads on my Jeep. Going to those again for my Tahoe the next set of brakes needed. Discs looked like brand new, even after 3 salty New England winters! Pads were awesome. Greta stopping and practically no dust. The discs were amazing, though!

NAPA makes nice stuff I used them in the past on another truck, but the cost is not worth it to me for this project. The overall braking performance of the truck with the 2020+ 4piston caliper set up in the front, hydro boost master cylinder, and stainless brake lines all around is stellar! Since this is just a basic replacement for the rears which probably do less than 30% of the work in this application I just want a quiet dust-free replacement. I'll send the calipers to be rebuilt and powdered to match the fronts but that's only because he's cheaper than buying new OEM replacements. I think these are the original calipers and at 280k I think it would be silly not to address that.

I still really want to come up with a way to either adapt the 2020+ 4 piston calipers to the rear or find some other budget-friendly (under $1k) rear brake upgrade that has an attractive-looking caliper.

Recently, I had an ABS code related to the right front speed sensor come up. The code cleared and was gone for almost a week. Running fine.

Found out the recent Right Front ABS sensor issues were 100% caused by failing hub.

Made a big POW and grinding noise driving home from Home Depot.
This is what I found in the morning... It spit out bearing rollers like a hockey player spits teeth!

I was able to pull the front half of the hub off by hand as soon as I got the axle nut removed.

Removing the back half of the hub was the fun part!
The only thing that got the hub to pop out was backing the bolts out about a half inch and beating the snot out of the bolts. I am so glad I bought the new bolts!!! I am keeping these to use again the next time...

This all that remained after the hub ate the ABS sensor...
New hub had sensor included.

Here is the new hub. I did not go low-grade, because I could get the better hub with 20% discount this week from NAPA. It was https://www.napaonline.com/en/p/BRGBR930304?impressionRank=1

Someone more knowledgable can tell me more...
It is an SKF part BR930304.
From a quick search, I saw some information that SKF was OE supplier to GM and may actually be Timken.
Let me know.

Usually with NAPA, the higher price item really is the premium product from the major OE suppliers. I have never been disappointed any time I went with their higher-priced items.

I still had time to get out and mow the lawn after I was done.
All is good in the neighborhood. No ABS codes and everything feels tight.

I hear ya! I had brake pads and rotors that got really bad and needed replacement in a hurry. I went with basic budget pads and rotors. The the caliper locked and had to get new calipers. Went with mid-level stock calipers.

Just remember, that the big brakes need more clearance. So you may need 18 inch or bigger wheels, if you don't already have them.

I think you’re right on the SKF info. If they’re not made by Timken, they’re as good as, from what I hear.

Calipers locking are up scary! Not sure how the pad or rotor quality could have caused that tho. I had a caliper lock up in another truck while I was heading to go camping in the Black Hills of SD. by the time I could find a safe spot to pull over the brake had gotten so hot that when I splashed water on the wheel it immediately sizzled off! Having minimal tools and being by myself I simply tapped the caliper with a hammer after it cooled off, it unlocked and the camping trip resumed. I did swap the caliper put shortly after the trip.

I've had the bigger front brakes for a year or so and probably 15k or more miles, they are the best brake upgrade I've ever done other than swapping to hydro-boost. They are also wearing very well, the pads are very meaty still.

Did the ABS and the P Brake light come on?

I do feel comfortable with my choice. With 20% off this weekend, I got the SKF (Timken) for $159, which was the regular price of the cheaper product line. So not a bad deal!

FYI for other members to keep in mind for future reference:
This is the source I was referring to... Dodge guy opened Timken box and found "SKF" stamped on the part.

Timken or SKF Bearings????

No. Just the ABS.

About two weeks ago, the ABS came on and stayed on. Scanned with Tech 2. Right front ABS Speed Sensor codes C0221 (circuit open) was the active code for that sensor when the light tripped. History showed C0222 (Signal Missing) and C0223 (Signal Erratic). Then the code cleared and never showed for the last week or so.

Everything was good until the bearing blew out and ate the ABS sensor when it grenaded. I knew by the sound and feel up front when it happened, plus seeing the ABS light come on, my hub was toast.

Left hub feels tight and sounds healthy. I'll keep an eye on it and replace at some point before winter. Since I already replaced a speed sensor on that side last year (has been code free since), I'll know the second I get another sensor code for the left side, that the hub is causing signal issues and showing early signs of pending failure.

Some overhead door techs are just assholes, and I'm qualified to say that.

I suggest LEDs in operators since the vibrations kill standard bulbs. In my day, we had to suggest "rough service" bulbs. But, they're pricey and that was before LEDs were common.

and those rough service bulbs don't last any longer at all from my experience. The coating just heats and peels off.. POS

LEDs designed to not interfere with remote reception? The ones "back then" were labeled as "rough service". Some brands labeled them specifically for garage door operator use to charge more. But, they were just regular rough service bulbs, ~~designed~~ marketed to better withstand vibrations.
