My left front brake pad (Chevy calipers) has a bit of howl when I turn a corner to the left. I know, not the best brakes. Pretty certain of the source as when I pulled the front wheel off and spun the disc I got a touch of the same howl at the same, apparently slightly high spot on the disc as it rotated. Bearnings are tight, brake brackets and bolts are tight, KO pins are properly torqued. Braking action is fine.

What's the easiest fix for this - sand the pads, apply some anti-rattle compound to the back of the pad, replace the pads?
