On cars we service at the suggested service intervals of 7,500 or 10,000 miles, we can estimate the remaining mileage quite well. As far as replacing the brake discs, there is a 'wear limit' for brake disc thickness particular to the particular vehicle. If your discs are worn to that point, they must be replaced. IF they are not worn to that limit, we would resurface the discs, IF they will still be above the service limit after resurfacing.
When my front brake pads wore out at 23,000 miles, the dealer informed me that the rotors had to be replaced also, and showed me the wear on them. I had them replaced. Now, at 32,000 miles, my trusted local mechanic tells me the rear brake pads need replacing - AND the rotors! I have owned 5 cars before this one, and kept all into old age, but I have never needed to change rotors before.
