Its not a squeal sound but more like a reverberation. Like something vibrating. A low pitch vibration. Other times it sounds like a cow moaning. And no farms are nearby either. Ha.

There could be something in the pads that got caught from the road
My sensors needed to be replaced 3 times in one year!! That is until I got Stop Tech BBK's and no more issues...
Or possibly the protection plate like donpb stated above...
I love the performance aspect but have never had soooooo many issues with brake noise until I got my e60

When I am braking at traffic speed, all is well, but then when I pull in a parking lot and am creeping along and lightly brake, I hear a noise coming from the right-side rear everytime I [lightly] apply the brakes. It's been happening for a couple of months. It doesn't happen all the time either. Usually if I go to park soon after a 45mph drive. If I wait awhile to park, it usually doesn't happen.
How can I trace what is causing the noise? Its gotta be either the brakes, calipers or rotors, right?
Oh, at first it used to sound like a cow moaning but now its like a grinding type low humming noise. Help!

Ok another thought just came to me. I feel it has something to do with the brake wear sensor for sure because the right-rear has a brake wear sensor and that's where I hear the sound. In addition; I feel the brake wear sensor is possibly touching the protection plate. I did not start to hear the sound until after my mechanic did an inspection on my car (brakes, calipers, etc). He may have inadvertently re-routed the sensor cable across the protection plate. I'll check it out and keep you all posted.

A caliper slide could be lose, or an anchor bolt. It could be the backing plate too, but unless you hit something in the road its really tough to bend/alter a backing plate. Hooch could be on to something with bad material, not only with the sensor, but sometime pads have a "hard" spot in them and it can take a few thousand miles for that "hard" spot to wear away.
