93 Nissan Maxima, Brake Dust Problems

Q: This isn't really a technical problem, but I'm sure a lot of people have a similar question. I've got a '93 Nissan Maxima that runs great. My question stems from the front wheels and brakes. I've got alloy wheels and because of the disc brakes, I get a lot of brake dust on the front wheels. I know about the weight shift that causes the front brakes to do a majority of braking, but what I want to know is if there is a way to stop the brake dust from getting all over the alloy wheels, is there an easy way to clean the unsightly dust off the alloy without damaging them?....

A: There are companies that make dust shields that can be installed on the inside of the alloyed/aluminum wheels. The shields redirect the brake dust so it will not collect on the alloyed/aluminum wheel. But a word of caution: many of today's alloyed wheels don't just look good they have a job to do. By design, the alloyed wheels direct air flow to cool the front brakes. Installing dust shields "could" cause the brakes to operate at higher than designed temperatures. The result could be premature brake pad wear, or even brake failure.

The best product that I have found for removing sightly brake dust is EG. EG costs nearly nothing and is easily applied at your convenience. Brake dust is corrosive so I recommend using EG weekly to prevent damage to the alloy wheels. Using a touch of detergent, water and EG is sure to keep your alloy wheels looking like new. You'll be surprised at the versatility of EG, it has many uses and is environmentally friendly. You just can't beat Elbow Grease at home, in your car or at work.
