Play in the front left brake calliper Bracket

Hey,
I have an 84 Interceptor 750 and there is some side to side play on the front left brake calliper, and calliper bracket (to the point were it looks like the bracket is starting to wear on the rotor). I was wondering if anyone could take some pictures, so I could try and figure out what is wrong/worn/missing? Or, if anyone had any insight on how this crazy anti dive moving calliper set-up is supposed to work?

Thanks,
Mez
