This will greatly depend on what kind of brakes you have and which parts you are trying to replace. Do you have disc or drum brakes? If you have disc brakes, do you want to replace the calipers, pads, or rotors? If you have drum brakes, do you want to replace the drum, or the shoes?

You would have to change the brake pads in your vehicle every 15,000 miles or sooner. It depends on how much you drive your vehicle. The more your drive, the earlier you have to replace the brakes.
