73 Cuda – Pass Front Rubbing only during light braking

Hi everyone thanks in advance.

I have been chasing an issue that is constant when I apply the brakes the pass. front disc has a fairly loud rubbing/squeaking noise.
I have...

1. Stock Rims and Disc Brakes
2. Checked 3x for metal shavings or signs of abnormal wear on disc
3. Removed the shim pads
4. Removed wheel bearing dust cap looking for wear / checking for looseness
5. When brakes are applied aggressively , no rubbing issues

Noise persists while light/normal braking, any ideas?
