I have been using raybestos on the fronts. The rears are still the originals, 144,000 miles. I have done the front pads four times. I ended up buying a set with lifetime guarantee and I keep an eye on them and replace them when there's only 25% left. The rear's typically are hard to keep adjusted properly and don't wear as fast. I pulled my rear drums off last weekend to see how much shoe was left, there was close to 1/4 inch left on all four shoes.
