Rumbling/Grinding on rear wheels?

[WM-S12]

recently i've started hearing this awful like grinding and rumbling coming from the left rear wheel. It sometimes comes and goes but it tends to pop up specially when I hit a bump, however the moment I use the brakes it stops the noise I've driven home using the heel toe method just to stop it irritating me.

It then doesn't even happen some days. I'm slightly curious as I got new discs on the back a few months back, alloys which are open to the elements and well I was out on some loose gravel mucking around. Any chance a stone or something has lodged up behind the back of the disc brake. It has the metal shield at the back so that's one guess as to what it is.

Im pulling my hair out, it makes a noise then it doesn't, when it makes a noise I apply the brakes and it stops happening. Diff....brakes. I've ruled out suspension. Not so easy to diagnose a problem using sound on a forum

frustrating

Had the same issues with one of mine and it turned out the guard was bent onto the disc.

I had the similar problem but the couse was a loose caliper. The guy in nissan service did not thighet it right and the calper fell of along with this thing that hold the brake pads and broke the e-brake cable. Fortunetly it was in a city so it happend at a very low speed.
