[TBLM235X]

I just had the M performance brake kit installed on my 435 xDrive this weekend; they were installed by my dealer (they did a great job). I had read many of the threads that included the comments about the ticking noise and the excessive brake dust. After much deliberation, I decided to go forward and get it done. I too hear the "ticking" noise if the windows are down and I listen for it. As noted, it is more prevalent when passing concrete walls/barriers. I don't find it really objectionable and may have not even noticed if I hadn't read the threads. I usually have the stereo up anyway and don't hear it at all so I'm not bothered by it as long as its normal due to the design. The brake dust is worse than I expected though; I really hope as I log some miles and they break in fully, that it lessens at least somewhat. I have my wheels coated with Opti-coat so I hope that makes clean-up much easier!
