I have had Dodge products for years and once had problems with pre-mature brake pad and rotor wear on my '94 Grand Caravan. Once the warranty period was over, I replaced with high quality aftermarket products. I currently drive a '12 Journey SXT/3.6. with about 15,000 km on it. I find it stops very well at this point with very little brake pedal pressure and none of the other problems that have been reported on this site. Usually fast wearing pads are made of softer materials. This will improve stopping distances and usually cause less wear on rotors. Harder pad material will last longer, but will require more pressure on the pedal to get the same stopping distance, resulting in higher temperatures on the rotors. This heat (and corrosion of the venting fins) is what is causing the rotors to warp. Most OEM and a lot of the aftermarket rotors are now coming from China with large variations in quality. I hope to get more than 30,000 km from the original set of brakes, but will not hesitate to replace with aftermarket whenever that time comes, warranty or not. At that time I will replace with high quality slotted and drilled rotors, but probably softer pads. I don't mind cleaning the dust of my wheels, they have to be washed anyway.
