GM customer service,
What is the solution to this? My 2020 Sierra 1500 had a caliper hang up. The inside pad on the driver rear wheel wore prematurely and the pad life sensor failed. I replaced all rear pads, rotors, and pad life sensor. I still get a "Service Brake Pad Monitor" message. I tried to reset the brake pad monitor. Both "Front Pads Installed" and "Rear Pads Installed" are grayed out so I cannot select that I replaced the rear pads.
