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.
In many cars, you can see the brake pads when you stand by the front tire. Look through the wheel rim openings to see the brake pads (see Resources for picture). Look at the thickness of the brake pad. If it is less than 1/4 inch, you need to replace the brake pad soon. If it is less than 1/8 inch, replace it now. If it is greater than 1/4 inch, you do not need to replace the brake pad.
