    Rotor hitting dust plate only when cold.

    When I first take off if I load the RR by taking a tight left turn I get a grinding noise. After about a mile or two it stops and won't do it again unless the car sits a good while. The rotor is hitting the dust plate at a little ridge on the rotor that's between the main brake surface and the emergency brake surface. I checked for play both in/out and twisting the tire but I'm seeing anything obvious.

    Wow, 2002 is an early join date!

    Maybe a bearing issue?

    Obviously you can just remove or bend the shield out of the way but I too would wonder why it cna move that far. I took that shield off to do the H6 upgrade - it is not at all needed.
