Ahh they are hayes nine i see from your picture. I have them on my bike.
All I can say is get used to doing a lot of adjustment with them. If there is rubbage on the rotor, i suggest you loosen the two mounting bolts for the caliper and then SQUEEZE hard on the lever, and tighten up while you are firmly squeezing the lever. This will center the caliper to the rotor. You might find you need to give it a ride or two and sometimes it'll sort it self out.
Also dont squeeze the lever without the rotor in, never touch the pads with your fingers and you can clean the rotor with Denatured Alchol or Metho.
Enjoy.
