been having various troubles with brakes lately. i noticed that i get odd brake dust patterns. after just one drive (when the wheels are clean) i can see clearly these streaks of brake dust on the wheel. the way it's on there looks like it was splashed with water or something. any ideas what this may be?

dude it is just the dust sticking to the rim as the rim is spinnng ( derr ) as the brae dust gets on it leaves that pattern
