Squeak : passenger rear wheel w/light braking, slow speed
Coming up on service (a little over 10K mi) and will ask dealer to inspect but just wondering if anyone else experienced this problem.
On extremely light brake application, only at slow speeds when coming to a stop (i.e. at only a few mph), I get a squeak from the right rear wheel. It happens regularly but only after driving about 1.0 mi or so. My wife was standing outside and localized it to only the right rear wheel. It doesn't matter what the outside temp is or whether the car was just washed or not. It only happens on light braking, never when brakes are not applied.

Yes, I have had this exact same issue with my 2008 C350. As per the service write up:
They found that the clip and springs for the emergency brake shoes were contacting the inner hub. They also found that the inner hub retaining spring for the emergency brake shoes and mounting clip were coming loose and allowing the shoes and clip to contact the inner surface of the rotors.
They replaced the clips and retaining springs as per LI Bulletin: LI42.20-P-049595.
This may or may not be the same issue with yours but at least it's some information to go on. Good luck.

Thanks for reference. Provided to service advisor and tech (they decided to order parts, just in case). However, still squeaking when I picked it up. Was hopeful but not really surprised. Will have to bring it back I guess and try something else.

Update: In case anyone else has the same problem. Tech installed new clips per bulletin referenced above but that did not fix it. So he replaced both rear rotors and pads and that solved it.
