This is just a general question. Disregarding all performance and brand issues, What type (organic, semi-metal, carbon, ceramic) brake pads cause the most wear on the brake disks? Like normal use, changing pads before you have to, which type pad will cause the most wear on the disk itself.

I am not interested here in discussing brands or performance, just the effects that pad type has on the wear of non-brand specific disk.

I know what you're after here and I don't know for sure but some of this will also involve the bonding material which can get deposited on the rotor and cause uneven ware.... which will cause the rotor to need replaced sooner. Cheaper pads of any type would tend to use a cheaper (and more) bonding material....... Just a thought.

Back to your regularly scheduled question.....

Yep Metalic and or Semi Metalic are the most abrasive in general street use.

Thanks, that sounds right.

Being in the ceramic insulation business, my vote is for ceramic pads causing the most wear

Semi-metallic cause the most wear. But frankly in my experience its marginal when comparing to ceramic. I have no experience with organic pads. I know you don't want to discuss performance, but I don't see how you can avoid it. Wear and performance are related and a factor in what you choose. Unless you are trying to settle a bet?

Been decades since I used any organics but as I remember the pads wear much faster which would tell me that they are softer and cause less wear on the discs. Conversely, I would assume ceramic is the hardest but really don't know.

I don't care about performance or dust on the wheels or any of those things. I use the car as a tool with replaceable parts. I do about 65,000 miles a year and replace pads at about 20,000, using "economical" parts.

I have noted that sometimes, in pretty short order the disks develop a pronounced "lip" around the circumference, but I never noted the type of pads involved scientifically.

Some pads seem to make the rotors only good for 3 sets of pads (2 turnings), and they need to be turned after each set. Some pads seem to only moderately wear the rotors and do not need to be turned each pad change and I can get 5 or 6 sets of pads out of a pair of rotors.
