Dragging Brake?

Tried out the GoPro today and filmed a bit of driving around hoping to capture the brake/suspension noise I've had for a bit now. After reversing, it seems like the brake pads are moving around in the calipers, then slamming to the front when I brake. There is 3-4 audible clicks when doing so. Also, there is a squeaking noise from a stop until about 20-23 MPH. Assuming this is brake related as well since it seems to vary with temperature. I have replaced the tension struts with M parts, no change. Wheel bearing? Control arm? Thoughts?

a lot of people hear the pads shift when they brake in reverse.

Are these oem brake pads?

What you may want to do is apply some BMW/MB brake pad paste on the leading edges of the pad backing plates where it meets the caliper bracket. The paste will help dampen the noise a bit.

They are OEM, I'll try the paste idea. Also thinking of switching to cool carbon pads and pulling my sensors out.

Thanks for the replies.
