I recently installed a set of Hayes Stroker Trail brakes with sintered pads on my bike and am using them with the Alligator wind-cutter rotors that were already in use, they had about 7 hours of use on them. I pulled the rotors cleaned them and lightly sanded them before installing the new brakes. The rotors are installed on a set of Mavic Crosstrail wheels using the Mavic center-lock adapter. The front disc is 203mm and during the bed in process it started to grab or brake harder at one spot spot on the circumference of the rotor, the same spot every rotation of the tire. I have checked the rotor and as far as I can tell the rotor is not bent nor does it rub when the brakes are not applied. The brakes are grabbing hard enough that I can see it being a problem on slow technical sections of a trail. The old brakes were Avid juicy 5 with semi metallic pads and did not grab or if they did it was not very noticeable. The Hayes brakes do have better stopping power compared to the Avids even though they are not bedded in completely yet. At this point I am going to borrow a set of dial calipers and check the thickness of the rotors and see if it is thicker in the area it is grabbing. Any thoughts as to a solution other than replacing the rotor?
