hey i have a 2003 350z enthusiast

i have been noticing my front wheels get dirty alot , from brake dust,
is that normal? may be i have been driving alot around the city??
or is my brakes going bad??

 

Both the brake pads and rotors an “expendable parts” designed to wear. Friction between the rotor and pad wears both creating minute particles of dust. The amount of dust depends primarily on the composition on the pads: some 350Z drivers report less dust with ceramic pads.

In summary, your brakes are fine.
