Squeaky brake/wheel - cause?

[Mr-B]

Thought I would try here for some guidance. As per the title I have a noisy drivers side rear wheel as per the video. The noise seems to come from behind the disc although difficult to tell. I thought I may be had a sticky caliper but there doesn't seem to be much drag on the wheel and the pads don't seem to be worn out/down to metal.
Any suggestions?
Thanks.

Does it disappear when you press the brake pedal?

Does it disappear when you pull up the handbrake when you are still moving?

If not, it may be the muck shield rubbing against the disc.

Breaking and using the handbrake doesn't seem to make any difference. Occasionally it will also disappear and be completely silent but it is there more often than not.

That muck shield sounds plausible. I first noticed it a few weeks ago when I was driving during that really wet spell we had and the roads were atrocious.

I know on E36, (and probably later) cars the slots in the brake back plate/dust shield would corrode, widen, and the parking brake shoe retaining pins would become loose. This was a common issue. The only way to tell for sure is to remove the wheel and (drum-in-hat disc). Then you would be able to see that the parking brake shoes are being pulled together by their springs, but not being held close to the back-plate. This means that the sides of the shores then rub and grate against the inner drum. If that is the case, then new back plates are required (I used an MG clip as a temporary fix). However the new plates can only be fixed by removing the wheel hub, and bearing. The best bet is to cut the new backplates in half to fit without undoing the hub, and re-weld them after fitting. Of course, that may not be the situation you have, but it was a known circumstance that I experienced. It could simply just be grit stuck in there.

The only thing I liked about your answer was the last sentence about the piece of grit The other stuff about removing wheel hub/bearings, welding, etc not so much. Might have a poke about on it tomorrow.
