Narrative:

I took my children up for a sightseeing ride. The visibility wasn't great so after approximately 30 min I decided to return to the airport (I77). I entered the pattern midfield downwind. Having already gone through my prelndg checklist I put in 10 degree of flaps. After calling base I put in another notch of flaps. After calling final I put in the rest of flaps and checking the VASI I had red over white. I noticed an aircraft in position for runup so I called a short final, did a scan and had red over white and 70 KTS. On touchdown I felt nothing out of the ordinary. I felt that both main gear were on the ground so I applied the brakes and pulled back on the yoke so as to make more pressure on the mains. At that time I felt like something gave out or I ran over something. Then the left wing dropped and a very loud scraping noise started. My first thought was a flat tire. I was going to retract the flaps but looking down at the wing I realized that as close to the ground as it was I better not. I was still rolling out straight so I figured it was best to get the plane into the grass. I applied full left rudder at the same time turned off the fuel and called to the FBO that I was on runway with problems and everyone was ok and to send help. I finished the shutdown and exited the plane. I walked down the runway to find the whole wheel-brake-strut assembly laying there. An instructor from the FBO gave us a ride to the FBO where after about a 20-30 min wait the owner showed up. He informed me that there was nothing I could do so go ahead and leave, that he would contact me. I have heard nothing to date.
