tesla replaced rear brake pads on Jun 8, 2020. noticed some scratch sounds from right rear 2 weeks ago, didn't pay much attention. . My wife drives the car most time. Yesterday, I drove it and the sound so loud, so checked myself and found that the brake pad is gone - metal on metal. 2mm router surface is gone.
the care is out of warrenty, what could be wrong? Tesla did the pad replacement last time. They are not cheap. I can do the pad, router myself, something else, I can't.
