Disc Brake Rub after new pads/rotors

[suncat]

Just last week I installed new front brake pads and rotors on my 95 C280. The pads on the front left are rubbing ever so slightly - not really causing any drag, but I notice a slight recurring noise when driving it now. Is this normal? Do I need to pull it apart and re-set things? I did spray the back of the pads with a quieting "goo" by Permatex.

Would love to hear about whether I need to adjust anything here, or just let them wear in. I am ready to do the rears as well, so anything I can learn about this would be helpful on the next time around.

Thanks, and happy holidays to all!
