Excessive brake dust
So I just got the Calipers, Rotors and pads replace 2 months ago on my 2004 GT Convertible. Before the replacement we had excessive dust on the front 2 wheels. I assumed that with the parts that this would resolve. But its still pretty bad. I've been letting my 17 year old drive her mostly. Could it be she is just too heavy on the brakes? THX

Yeah, brake dust depends on the quality of the pad, and type. Depends how dense the
pad material is, what it's made of, and what else is in the material.
The more "metallic" the pads are, the worse it is. The steel fiber content in pads
can be up to 30%. The fibers are abrasive, that is what scratches your brake rotor
and that causes the dust. SO, yeah, the brake dust that we all see on our rims is
92% iron. Simply put is in caused by abrasion of the cast iron brake rotor by the pad,
and secondly the fibers from the semi metallic elements of the brake pad.
Pads that are made with Twaron or kevlar fiber are only (usually) available as upgrades.
The reason manufacturers opt NOT to use these more expensive pads, is simply for build
cost purposes. These pads last longer too, are less abrasive against the rotor, thus less
brake dust.

The 17 year old probably hits the brakes later and harder than you, too. Sometimes that can accelerate it. Or they used some A/M pads and rotors. If it went to the dealer, I doubt that though. Good luck! Wash her more!
