These are aggressive pads that hold up well and wear out well. At about 7000 miles I had to remove the Centric 121.33100 C-Tek rotors and machine them for warpage. The pads wore evenly and looked like they were about 50% worn. I attribute the buckling to poor metallurgy and insufficient rotor thickness, but it could also be due to excessive lining friction. If you use these pads and ride like me, I would go with a better than stock rotor.
