Slop between lugs and front rotor - Normal?

What is the reasoning for the slop around the lugs and the front brake rotors? I've never seen this much space between lugs on a car before. The rotors usually fit the lugs snug. I think the noise I have when coming to a stop is due to the rotor shifting on the lugs. See pictures.

 

Expansion and contraction occur as temperature changes.

 

I’ve always seen it.

 

It's normal. What needs to be tight is the centre of the rotor to the hub. Once the lug nuts are torqued the rotors should stay put.

 

If your rotors were moving under braking you would see some damage or wear on the lugs and the rotor holes.

 

If the rotor is sliding, you can confirm by looking at the backside for slide marks. If they did slide, the fronts will stay in place after the first stop since the truck is not front wheel drive.

 

Each stud tightens down with ten thousand pounds of force. It shouldn't move much. Even if it did, virtually all the time the rotational force is in one direction only (drag of the brake pad) except when backing up.
