Trying to put a time or mileage limit on how long brake pads and rotors should last is harder than trying to predict what kind of gas mileage you should expect. Brake life depends on how much we drive, where we drive (think city versus highway) and how we drive (meaning lead foot versus slow and steady).
As a guideline, brakes will wear out much faster if most of your driving is in a major urban area where stop-and-go is the rule, as opposed to those who spend most of their miles on the open road, where they might not touch the brake pedal for an hour or more.
If you drive in Boston, New York City or Chicago and spend more time stopping than going, you could need new brake pads every 15,000 miles. If you live in western Iowa and commute from Moville to Holstein, your pads could last three or four times that.
But if you're a driver who frequently applies the brakes when it isn't necessary — or even drives with one foot on the gas pedal and the other on the brake — it might not matter where you live. Your brakes are going to wear out sooner than later.
