Rattle, Rattle, Rattle. Alcons?

[GregorFuk]

I'm loving my CSL but if I put the window down when running at low speed on a bumpy surface it sounds like a bag of spanners! Not Good.

However. I've noticed that just the lightest touch on the brake pedal will stop the rattling. This makes me think that the noise is coming for the Alcons I'm running on the front. Could it be the pads rattling in the calipers or the disks rattling on the bells? Or all of the above. Has anybody who's running Alcons suffered the same issue and resolved it? Or is it something I have to live with?

A quick peak through the front wheel tells me that I do have anti rattle springs fitted in the caliper. Well the offside one at least, I never checked the near side.

I notice from this month's EVO David Yu may be suffering from the same issue.

Any advice would be greatly appreciated.

Cheers
