For about the past day or two while driving I been hearing a whistling sound that would disappear when hitting the brakes and it just got louder. Got up early this morning and checked to find the rear pads /rotors were toast. Didn’t have time to order replacements online as I needed to use my truck for work this afternoon so I headed to autozone, got the Duralast gold ceramic pads and 2 new rotors $175 and change out the door. (Powerstop rear kit from rock auto is $129 and change shipped). The old pads have a “C” stamped on the back plate so assume it’s centric pads. Anyways, I removed the calipers, rotors, pads and gave everything a good cleaning w brake clean and a brush. I pulled the caliper pins and they were dry as a bone so I cleaned and generously applied sylglide (still have a tube that is at least 6 years old) Buttoned everything up without any hiccups and drove it about 150 or miles. These pads are good perfect for daily driver truck. Did not take any photos of the new parts but they look the same as any.
