Noise during braking - what is this (video link included)

I'm hoping y'all can help me diagnose this noise my 2023 TRD OR is making when I brake from, say 30 miles per hour at a stop sign (going straight) or making a right or left hand turn. In the video linked below, the noise occurs about one to two seconds into the video. Here are a few related points:

1) The noise sounds like a metallic scraping or rattling sort of sound (not the low-frequency tire noise or the click/thunk sound at the end of the video).

2) I have all the skid plates removed, so it's not a skid plate rattle.

3) The noise happens when braking in a straight line, so it does not seem to be steering-related (I realize in the video I'm making a right turn at the time it happens, but it would have done the same thing without the turn.)

4) The noise happens during mild to moderate braking (probably at the point when the speed has slowed to about 5 or so miles/hour) and seems to coincide with the point during the braking process when the low-frequency tire noise is at or near a maximum.

5) I can't tell while driving whether the noise originates under the vehicle or in the engine compartment.

Any ideas are appreciated!

Hard to make out anything definitive from your video.

if you have the means, put it up on stands and look around loose components, signs of rubbing, etc.

haw many miles on the vehicle? Mods?

 

Sounds like an exhaust metallic sound. Check hangers and what it may be hitting against.

 

So more info needed. Original brakes or aftermarket? Are calipers clean?
How many miles on these pads? What is approx. pad thickness?
Could the pins holding the pads in the caliper be dirty or rusty or dry (lube gone)? Did the antisqueal shims that press the caliper piston to the pad itself get properly lubed?
Sometime pads can shift in caliper when braking and make a metallic clunk?
