Default Cranking sound when braking at slow speeds

I've recently noticed this issue when braking under 20mph. You can hear a cranking/grinding sound in the background. Sounds like the front left wheel area.

Not sure what it is. Lexus dealership didn't hear anything.

What I think I hear is something like a knocking sound that seems related to the car's speed, i.e., the knocking sound slows as the car slows. Do you feel any vibrations in the steering wheel or the brake pedal?

But the sound seems to have a tinny metallic sound to it. I am at a loss to even make a guess.

I don't notice any vibrations in the pedal or wheel. It seems like it's only a sound.

I've searched for the issue and some say it's either control arms or a warped rotor. I've never heard of it being this bracket. I never lowered my car either. But I can look into it.
