i don't have a picture.

did my brakes, rotors, and bearnings today...as i took off the dust cap there was this tiny copper colored piece of metal coming out from the center of the spindle? so this metal thingy makes contact with the inside of the dust cap?

not a very good explanation. i've never see this. i'm sure someone has. what is it and what does it do?

Your explanation is very exactly ;)

This contact prevents disturbances in the radio. I am no expert in the area, but simply said, its because of the turning parts of the wheel suspension, that can occur electrical disturbances in the radio. With the contact the turning parts are grounded.
