Disuse can be as bad as overuse. Our Wranlger sat parked on a grassy area for weeks at a time and the rotors rusted. If you're not parked on asphalt, concrete, or in a very dry area, expect the rotors to rust -- and they will tear up the pads.
At 240,000 miles I'm thinking about getting my second set of replacement brakes on my Patriot. They were replaced at about 100,000 miles and the replacement set (from FCA dealer) have gone 140,000 miles. No complaints on my part, but I can tell they aren't as good as they once were.
Ball joints do seem to be a weak point on Patriots, but I replaced the ball joints on my Bravada twice before 80,000 miles. First replacement was under warranty, I paid for the second and there wasn't going to be a third set since I was also having trouble with my fuel injectors.
When a vehicle gets to be 6-7 years old, ya gotta expect repairs.
