Didn't have time to post earlier.
Your intuition is right. Barring rare occassions,
brake dust is THE major source of wheel dust.
For most convetional vehicles with disk brakes,
the front brake pads are *bigger*. You can simply
take the wheel rim off to take a look. Bigger
pads, more dust!
I don't need any other physics/engineering proof,
all I did was to switch to different kind of
brake pads. Try it yourself. Switch to Axxis
brake pads, available from
http://www.zeckhausen.com/
The pads are made of different materials, the brake
dust generated from these pads is much finer grained
than regular pads. For about $150, you can have
clean rims forever.
Consider this when it is next time for you to change
the brake pads.
