I thought I’d update this thread because the second set of Ceramic pads lasted a few months & 900 miles while using brand new AVID HS1 Rotors, again, 95% road riding.
While having a look on their forum, I noticed I wasn’t the only one having issues with their ceramic pads.
There are no pictures, but he said the pads last a few hundred kms and nearly broke his XT-discs, so no lightweight disc there.
I wasn’t going to bother contacting DB, but after the second set of pads wore very quickly, I sent them an email with pictures.
They are now going to send me new pads and discs, and they want to check out my discs and pads, so I will be sending them off.
So, not a great experience with these expensive ceramic pads, but it does seem to be a bad batch because even the cheap ebay Sintered ones I got for a few pounds a pair lasted twice as long and that was through winter riding.
