I've often read on forums about the EBC HH sintered pads and how hard they could be on rotors, so I wanted to share this with someone who was considering using them. I'll qualify this by saying that I didn't measure the rotor thickness at the time I switched from OEM pads to the EBC HH ones, so I can't give any precise numbers on wear and tear on the rotor.
In Feb 2017, when I had 32,219 miles on my bike (which is a 2014 Super Tenere, not that the type of bike is really important here), I needed new brake pads and decided to give the EBC HH ones a try. As I said I didn't measure the rotor thickness, but I did check the rotors for any excessive wear, gouges, lips, etc and didn't find any.
Six months later I'm checking the rotors for wear with a micrometer. The rear rotor was down to .1529 (minimum rear rotor thickness on an S10 is .18 ), and there was a very pronounced lip on the inner surface of the rotor. At this point, the EBC pads had 8,737 miles on them. The pads looked virtually new. I've attached a few photos of the lip that was worn into the rotor.
I put a new OEM rotor on the rear, and swapped out the EBC pads for OEM ones.
The EBC pads performed well, but not noticeably different than OEM ones. I'm definitely leaning towards the "EBC pads eat OEM rotors" camp, though, and I don't think I'll be using them again.
