My front end shakes when I hit the brakes.

What is your question?

I took off my tires and looked at the rotors but they were almost brand new not warped. I saw on my passenger side it looks like the tire is rubbing the strut. So I then thought maybe the tires were too big, but I checked with the manual but they were factory spec. I then thought the tires are out of balance, got them balanced. I started driving slammed on the breaks and seemed like the problem was gone. I drove to 100mph and slammed on the breaks so I thought the issue was gone. Then shortly after the problem came back only when I brake hard, so I have been braking lightly. So now I think it's the struts, what do you guys think? I would appreciate any help.
