Why do my front wheels have so much brake dust on them?
The composition of brake pads has evolved over time as lighter vehicles and environmental concerns have increased. Finding the ideal recipe to increase brake pad life, brake performance, and brake noise reduction is difficult.
Unfortunately, brake dust is a byproduct of brake wear and brake pad degradation is inescapable.
As the metallic particles on your brake pads wear off the pad’s surface as they heat up, they acquire a static charge. That is how the black, metallic dust adheres to the steel and alloy wheels as well as other components of your car. Additionally, those petroleum adhesives have the potential to form a coating that sticks to your wheels.
Cast iron brake rotors can also contribute to brake dust. As your rotors deteriorate and fall off, iron specks acquire a static charge and stick to things like your wheels.
