Also, after looking at some pictures from last years car they didn't have a normal f-duct (which I never really noticed last season) so I think it may be some sort of aero stalling device controlled by the drivers knee, but I'm also confused as to why it was only on michael's car.
As far as I am aware brake bias settings MUST be mechanical due to the regulations - i.e. hand operated using a lever or screw type design off of the steering wheel. Not sure why but that was my understanding anyhow. I recall Ferrari's mechanism being on the right hand side during Kimi's days.
Either way, it's probably an innocent brake bias switch in the cockpit and the duct there to keep the Schumi cool.
