As the title says, I’ve heard my car make an extremely loud screeching noise twice. The first time was about 30 seconds after I started driving, and the second happened around 20 seconds later. After that, I drove for about 5 minutes and didn’t hear it again.
I also noticed some rust- or gravel-like crumbs inside the front right rim, but none of my other rims have this issue. Could the noise and this observation be connected? Any ideas on what might be causing it?
Gotta be something stuck in your brakes or extremely worn pad.

Okay! Thank you!
Or your wheel is loose.

Possibly. Your wheel holds the brake rotor in line. It’s unlikely but you definitely need to look at it before anything gets worse.
@Adley
Sounds good, thank you.

If you hit up a tire shop like Discount Tire, they will usually check your lug nut torque for free.
Probably a CV axle boot torn, threw grease all over the inner rim.

This is it. Grease is trapping sand and debris from the road.
I have an issue with tiny pebbles getting stuck between my backing plate and rotor, causing a horrible screeching sound. I’ve bent it back a little bit so that way tiny pebbles won’t get stuck and will fall back out.

That one looks good.
Drive through somewhere being freshly paved? Looks like asphalt to me.

Not really, but the landscapers were blowing scrap next to my car for about 10 minutes straight. The only weird part was it was the only rim that had all those gravel-like pieces in it.
I’d try to get it on a lift. Most tire shops will look for free.
Judging by the huge score mark going around your wheel, I’d say you’ve got a clearance issue somewhere. Start with taking the wheel off and checking the brakes, tie rods, everything.
Could be a worn pad. Easiest thing to check first, I think.
How many miles? Wheel bearings will do that. The disc shifts enough to contact the brake carrier. Do you hear any noise when traveling in a straight line? It won’t always be a grinding noise; it may just be a low pitched hum.
Caliper loose & out of position? Inner brake pad thin enough to slide out of place?
