My 2009 E320 Bluetec front ring wheels gets dirt in less that one week.
This dirt is a kind of a dark (brownish) dust impregnated allover of the front ring wheels.
Passing my finger over the dust area it seems to come from the brake pads and /or brake rotors. The rear wheels does not have this issue. Only the front on both sides. This dust will come out only washing the wheels with a brush and soap. Any idea what it can be?

It's brake dust. Normal for disc brakes. Some wheels collect it worse than others. Front wheels are typically the ones that show it the worst.

Akebono Euro-ceramic pads have low dust or dust that blends with aluminum color wheels. They perform well after the first few stops of the day.

Akebonos:

New "Akebono" Rotors (They're "Zinced" to prevent corrosion)
AND
New "Akebono" Pads CERAMIC

Will fix that difficulty right Away!

The rotors and pads compliment each other...

_____________________________________________________________
Traditionally semi-metallic pads and full metal rotors provide the most stopping under repeated braking. [HEAT IS Everything !]

AND Everyone says Ceramics JUST DON'T DELIVER under heavy stress.

BUT the Akebono "Combo" provides (ALMOST) dustless Braking with VERY
Acceptable Performance!

PLEASE remember to follow PROPER Break-in procedure to ENJOY full Braking Power with ANY New Brake set-up.
