Maybe this is why...

...you're not supposed to mix OEM brake pads/rotors with EBC rotors/pads.

These pictures are brake pads put on the bike, new, one month ago when I changed the rotors.  They are Honda OEM and the rotors are EBC.  Less than 1000 miles and they are 80% used up.  Apparently the EBC rotors are hard stuff.

This leads to the conclusion that if you put EBC pads on with the stock rotors, you'll chew up your OEM rotors.  Somewhere in the past I'm pretty sure I did just that which is why I now think my rotors wore out prematurely.

The above comments relate to sintered pads, not organics.

as you said, maybe that is the reason.  They are designed to match up oem and oem and aftermarket to aftermarket.

The point you make about which pads, is significant.

Even though some will berate organic pads, organic pads are the most rotor friendly pads you can install.

Organic pads may cause you to have to use more force to attain the same stopping effect but the difference is negligible.

Sure, organic pads wear out at a quicker rate when compared to other types of pads but that is what you really want. The rotors stay pristine, all the wear is on the pads.

Organic pads are inexpensive. The last ones I bought were four sets for forty bucks. Match that with metallic types or the new kevlar pads.

Ricky-D,

I know you're a proponent of organic pads, but from everything I've read, they only achieve full stopping power after they heat up.  Now, this may only take a few tenths of a second to achieve, but for how and where I ride (the DFW Metroplex) I want those few tenths on my side of the stopping equation.

I'd rather spend extra on sintered pads when they wear, and on new rotors once every 50k miles than give up the advantage, however small.  And, now that I know WHY you match pad and rotor manufacturers, I may not have to replace my rotors again.

Hayhauler, this may help:

Basically, organic pads are a made of a non-metallic compound such as Kevlar.  Sintered brakes are a metallic compound (ideally of a material softer than the brake rotor) fused together to make the pad.
