CCB’s chirping when not braking..

[Colinv6]

I had a lightly used set of CCB’s retrofitted earlier this year, all done by BMW, including the booster and coding.

The car and the brakes are amazing. Feel great and are generally silent, however I’m getting a faint chirping while driving around with the window open, which goes silent when I brake. It’ll then stay quiet for a little bit of driving and come back.

It’s actually worse when turning one way, and disappears when turning the other way.

I’m tempted to try new pads, my previous car with factory CCB never did this.

Mine does this on occasion. Same behavior, louder when turning. I find it goes away when I go for a spirited drive, so I attribute it to dirty calipers/pads and it burns off. I’ve considered the Porsche piston shim things, but haven’t got around to it.
