I’ve got a 2020 RST with 26,500 miles and mine shows 76% front and 85% for the back. They’ve been squeaking about two weeks. Pretty sure they need to be replace with soon the stop and go Massachusetts driving I do. All we need to do is pop wheel off, there’s a pin through the caliber and a metal bracket that holds the pads in. Pop those out and slide new pads in without removing rotor. Problem I’ve seen is by doing this, truck will detect new pads and go into limp mode with a max speed of 43mph and you need a scanner to clear. I came to post about asking if anyone had problems with installing brakes
