Strang Brake Rotor Problem

I recently got some Brembo Blanks and Hawk LTS pads. After the install I tried to do some of the techniques mentioned on the back of the Hawk box to break in the pads. I accidentally hit the brakes really hard one good time. After this I starting hearing a repetitive clunking while braking. The clunk changed with the speed I was going as I was braking. I immediately went home and took off the tire. After some inspecting, I realized I could grab the hub and spin it back and forth while the rotor remained still. The clunk I heard was the rotor hitting my studs. The rotor was not seated on the hub properly. I tried everything I could to make it sit right but every time I test drove it, it did the same thing. Did I warp the rotor by braking too heavily too soon? Is it no longer seating properly because it is warped? I can't believe that braking hard one good time could ruin a new rotor. What if I was driving after installing my brakes and a kid ran out in front of my truck? Any input is appreciated guys.

 

Im far from an expert on the matter, but my recommendation would be to pull everything apart and walk back to step 1. The re-assemble ensuring that everything is properly in its place, torqued down, and greased/lubed as necessary. I doubt stabbing the brakes would've warped your rotor.

So replaced the rotor with another Brembo from Napa and it is fine. Maybe it was a defective rotor? Weird...
