How long do brake pads last on average and does driving style effect their lifestyle?
Brake pads are designed to last several thousand miles, so you should be able to get at least a couple years' worth of use out of a set. However, exact mileage intervals for installation can vary widely depending on your driving habits. If the majority of miles stacked up during city driving near Jasper, IN or Lawrenceville, IL, then you'll likely need new pads more frequently. If it's mostly highway driving, your pads will probably last longer.
How often brake rotors need to be changed. Does weather effect this?
Brake rotors usually last quite a while -- some sources estimate up to 70,000 miles. However, this can also vary from car to car. Some vehicles may need new rotors in as little as 15,000 miles. Weather can affect the wear and tear of rotors via the freezing and thawing process and rust accumulation.
