Utter confusion from breaking noise

Hello,
This tundra is new to me and I am lost to what this sound is. My theory is that it has something to do with a pad but then the whistle- like noise throws me off. It is utterly loud. It is not continuous while I am driving and likes too really scream after a long day. I have plans to take it into the dealership to get it checked out although I have always found that it can’t hurt to reach out to the community as well. Excuse the bad language in the video. There are wheel spacers on it that were not put on by me, I have not gotten around to taken them off yet. I do not know if that could also contribute to the noise. Much thanks!

That first clip is difficult, but in the second it sounds like brakes (wear indicator rubbing), or possibly the heat/brake shields might be making contact.

Keep us posted.

BTW, WELCOME to the forum!!

 

Can't help you with the problem but WELCOME FROM TN!!!
