What specs did you check? |

Sounds like steering head bearings, but more info needed like Etennuly said. |

Three main things can clunk upon braking: Steering head bearings Rotor mounting hardware Front engine mount I'm betting head bearings first, rotor hardware second, and engine mount third. |

Also if the internal bushings in the forks are broken/worn it can allow the slider to "clunk" against the tube. Lots of wheelies? |

Yeah, FL, but that one is easy to diagnose. That and when you slam on the brakes and your wife comes flying up from the beaver tail to merge with you. |

Yes, I rushed my bike in a panic to the dealership the day before my homecoming trip because it would "click" when I put the front brake on hard. I could reproduce it by holding the bike at a standstill with brakes on and bouncing the bike up and down on the front wheel. I retorqued the steering head bearing and that did not help. It turned out to be normal. The front brake rotor moves, and will bang into the stops making a thunk noise. The spaces between the rotor and the stop accumulate brake dust and this muffles the noise. But if you wash the wheel off really well, like I had done when I changed the tire, it will click until you get some more dust in there. I was skeptical when they first told me this. But the noise has gone away, just like they said it would. |

Rotor moves, or the pads move? |

Rotor moves. I don't believe the pads can move because of the pot pockets and lock pin. |

No tolerances? |

because of the pot pockets and lock pin He-he....You said "pot pockets". Did you mean "hot pockets"? no tolerances That's right.....zero tolerance. (Message edited by etennuly on October 28, 2007) |

Mmmmmmmmmm. Hot Pockets! The tolerances appeared to me to be pretty tight. I could be very wrong, though. It's been known to happen before. |

Quick check for rotor bushings is to grab the front brake lever (when you're already at a standstill!!) and roll the bike back and forth a bit, seeing if the wheel shifts around the drive pins that hold the rotor to the rim. If you can see the rotor move in relation to the rim a lot, you may want to have it checked for bushing replacement. I perform this little test on my S2 every once in a while, just to make sure my rotor isn't gonna fly off the carrier when I least expect it, LOL. |
