New Brakes/Rotors New "Clunk" Sound

Installed new Powerslot rotors and hawk pads over the weekend. All seemed fine until today I noticed a kind of "clunk" noise from the front while braking. Slow speed, backing out of driveway. Will pull the wheels tonite to check it all out, but anything specific to be looking for? (Bolts tying calipers to brakets of course..) Any ideas would be welcomed!

If the noise is only when you change direction, ie. reverese then drive or vice versa, then it's probably normal. If it is a "clack" sound then what you're hearing is the pads shifting slightly and hitting the caliper.
