You need to check the brake lining condition about every 5,000 to 6,000 miles to see how they are wearing. Every time you rotate tires.
Brake wear can vary greatly from one driver to another. I have 108,000 miles on mine with the original front pads and they still a lot of material remaining. Some SVT owners may only get 20,000 miles. Checking them regularly is the only way to keep track of them.
