Did you bed the pads in initially?

If not, try that 1st. Should problem persist:

To narrow it down-- switch pads from left to right and see if the noise follows the pad....

Will narrow down whether it's pad or rotor related, but if switched, rebedding will be necessary.

Might want to dab the ABS sensors w/ some hi-temp lube just for shots and goggles.
