Hello, I did visually inspect the back brake pads/caliper brackets and calipers. I removed the slide pins and re-lubricated with sil glyde. I Think I have narrowed it down to the parking brake, as they no longer work and I found a small piece of the shoe in my driveway the other day where I park my truck. Does anyone know if I can service the parking brakes without any fancy computers to release them? Thanks in advance.

I have a 2021 Silverado 2500HD Custom Crew Cab with about 55,000 miles. I use this as a daily driver, plus to tow my 7,000lb camper 8-10 times per year. Yesterday when I put my truck in reverse the rear brakes made a growling sound, and this morning they made the same growling sound. After I slowed down and hit my brakes the sound went away temporarily and then came back at low speed when turning into a driveway. My brake pad life sensor (which I don't know how they work or understand) went from about 80% all around yesterday to 0% front and rear today. There was also a faint brake smell coming from the rear, nothing from the front. Any help would be appreciated. I should add that I have always done my own maintenance until now, with all of these electronics. Thank you!
