I recently started hearing some squeaking noises when coming to a stop and reversing. Saw that all 4 of my rotors have surface rust. They’re all literally brown/copper colored. I know hybrids use regenerative braking but I managed to hard brake / put the car in neutral from 40-50MPh to a stop so the brakes activate but the rust is not coming off. I’m not sure if anyone else has similar issues? The dealership I go to is backed up for 3 weeks which sucks immensely.
