noise from rear brakes
I recently took my 2011 E92 M3 to the dealer, due to a metallic tapping/cracking noise generated from the rear brake area. It sounded like similar to something brushing the rotor dust shield, but was a bit more “springy” in sound, and was directly related to the rotation of the drive train. The tech I talked with said he had seen several identical issues with new M3’s, and its cause was e-brake related. He found that cleaning and lubricating it fixed the problem. He did the work yesterday, and so far no more noise. But, since it was somewhat intermittent, I can’t yet say for sure it’s fixed, but if it remains quite for a couple of days, that may be conclusive of a remedy. I was curious if others have had or, may currently have a similar problem?

Thanks. I searched again and found a thread this time. Seems the resolution posted there confirms my tech's assumption of an e-brake issue; good to know. I ruled out the stone-behind-the-shield possibility first, and I knew it was not a differential noise, but I didn't think about the e-brake.

I also had this noise and was convinced it was pebbles in the brake shield.
I actually removed my rear wheels and inspected the shield, etc, etc. I found nothing....no stones, etc. It is very intermitent. The next time I am messing around back there, I will inspect the e-brake assembly and lube as required to see if that stops it. Good to know...thanks for the info!

What ceramic brakes? But in any case, that would certainly not cause the noise I experienced. I drove my car more today, still no noise, so it appears the tech was correct, and it was an e-brake issue. If your car has the same noise, and a tech told you it was ceramic brakes (which would have to be after-market), then you might consider another service provider. Any experienced mechanic would know that would not be the cause (again, if it is the same noise).
