Black Grease on Front Wheels

Hello all,

My car has thick black (what i think is) grease all over my wheel rims on both front wheels. Does anyone know what this is all about or why?

Thanks for any help,

Linda

Probably brake dust.
Have a look:
Why do my front rims get so oily?
Brake Dust Shields?
Brake Dust
Hope it'll help.

Without brake dust shields (which smart says not to use), all Mercedes-Benz products get dirty wheels, especially the hard-working front disks. In the case of the smart, the rear brakes are drum-type and don't produce the dust that the front disks do. It is all a matter of the company that M-B sources their disk brake pads from. There are cleaner aftermarket alternatives, though some may have a lttle less stopping power or are noisier (squealing or chattering). Very hard compounds can score the disk rotors. It is all choices.

I solved the issue in an unintended way. I bought genius rims, they somehow seem to not get as dirty with that oily drake dust... go figure!

Rule #1...... Any modification you do to your vehicle is your responsibility.
Rule #2...... No one is smart-er than Mercedes Benz.
Rule #3...... If you don't understand Rule #1, see Rule #2.
Rule #4...... If you don't agree with Rule #2, see Rule #1.
Rule #5...... Brake dust sucks

I had the same issue with dirty front alloys due to brakedust, and over 4 years the alloy surface became pitted and the surface was bubbling up from underneath, so I got them powdercoated black and killed 2 birds with 1 stone.
