I've had good luck cleaning my rotors with a brillo pad & brake cleaner. Wear gloves! You can also buy brake rotor hones to help strip all the crap off & give them a "like new" finish. |

yeah all the deposits are shaking the fairing like crazy under heavy braking! |

Also ensure that each mounting point of the brake to the rim is moving freely. These can get gunked up and cause issues. Spray behind the rotor with some brake cleaner, helps a little. |

You should be able to remove the deposits from the rotor by repeated hard braking. See here for a recommended procedure: http://stoptech.com/technical-support/technical-wh ite-papers/uneven-pad-deposit-removal In my experience, ceramic pads are the worst (and generally only) offenders when it comes to leaving deposits on rotors. I'm guessing that the Ferodo pads aren't ceramic, but I would strongly recommend changing to a different brake pad compound. I'm a big fan of the Dunlopad SDP993 pads, which I've got on my 1125R. Several thousand miles, no deposits, and great stopping power. http://www.ebay.com/itm/DP-BRAKES-HH-BRAKE-PADS-SD P993HH-BUELL-1125-CR-R-08-10-/230792355890?pt=Moto rcycles_Parts_Accessories&hash=item35bc4be032&vxp= mtr (Message edited by thefleshrocket on June 06, 2012) |

Syonyk nailed it: Brake rotor surfaces are quite rough under a magnifying glass. Many different substances can become imbedded and create the "hard spots" that cause jerky braking. A lot of brake rotors have been replaced that just needed cleaning. |

That rotor looks aweful purple to me. Id lift it up, spin the wheel, and ensure the caliper isnt binding, just to be sure. |

Brake rotor hones have been around forever, and can be found at most auto stores, or even Sears for less than $30. All of them are "flex-hones"... |

To me, that rotor looks completely unused, and a racing brake pad is only going to make the situation much worse. After you clean the rotor buy a soft, street pad designed for non-aggressive riding. |

@jdugger alot of my riding is pretty aggressive not track aggressive but more than "street use" |

You aren't using the brake hard enough for a racing pad... |

It looks like you have hot spots, which cause the metal to harden and the pad not to grab. Hot spots on a flywheel cause horrible clutch chatter and I assume the same with brake rotors. Do you have a larger picture of your rotor? |

I had the same issue when I replaced my pads. Rebuilding the caliper solved the dragging issue. Bought the kit from American Sport Bike for $68 with pistons. EB R has the kit for cheaper without the pistons. |
