Wanting to keep the rims clean is one objective. But it's not necessarily the (overriding) best objective when it comes to braking. One of the more expensive brands out there is Mercedes. I've often noticed that the front wheels on them are caked with brake dust...........Gee, maybe they decided that dirty wheels were a better option than pads that wouldn't create that problem but would at the same time not offer the stopping power as the other.
On another related point.........You need to be sure that the pads you select are (COMPATIBLE) with the rotors you have. Years ago, my little Toyota pickup went maybe 40,000 miles before I had some warpage.
Had the rotors turned and a new set of pads installed and didn't get to 20,000 as I recall before the warpage returned and I had to do it all over again. The answer was that the pads I used were not meant for the stock rotors and thus wore them out before a stock set of pad would have.
When I replaced my rotors with US made drilled slotted ones they came (optional) with ceramic pads. After installing them the truck was almost dangerous to drive as the brakes were useless.
I talked to a local shop and they told me to get Delco pads. They said they have never had a car come back with braking issues with Delco pads and have had issues with many other aftermarket pads. I bought the pads locally, had the rotors cleaned up after the other pads just glazed them up. Brakes were solid after that. I have had them on for two years now with no issues and never have a dust problem. This is my daily drive so it get lots of use.
