Rotor and pad bedding procedure/problem

[01sapphirebob]

Ok, so me and stretch finally got my rotors and pads installed and we went out to bed the pads and rotors. We came across an interesting noise/sound. When stepping on the brakes with moderate pressure there appears to be an almost knocking sound. Like you can hear the rotor "hitting" the pad. We got about 1/4 of the way through the factory bedding procudure and headed back to the house to check things out.

Everything seems to be in working order. All bolts were tightened to service manual specs. There doesnt appear to be any hangup in terms of a stuck piston. We picked the front of the car up and the wheels appear to spin freely except in one spot on both sides of the car (front) where it almost seems like the rotor is catching the pad. After a couple of phone calls we went back out to finish the bedding procedure but the car is still making the noise. There is NO vibration in the steering wheel when this is happening.

Any ideas/suggestions? One person we talked to suggested a more aggressive bedding procedure but ill take all the advice i can get.

The setup up front is OEM rotors (which had a zinc coating on them) and Hawk performance pads.
