Is the black dust on the wheel hub a problem with the brake pads?
1 Answers
The black dust on the wheel hub is not a problem with the brake pads. Here is some relevant information about brake pads: 1. Classification of brake pads: Asbestos brake pads (basically obsolete), semi-metallic brake pads, low-metallic brake pads, NAO formula brake pads, ceramic brake pads, and NAO ceramic brake pads. 2. Ceramic brake pads vs. traditional brake pads: In traditional brake pads, metal is the main material that generates friction, providing strong braking force but with higher wear and a tendency to produce noise. After installing ceramic brake pads, no abnormal noise will occur during normal driving. Since ceramic brake pads do not contain metal components, they avoid the metal noise caused by the friction between traditional metal brake pads and their counterparts (i.e., brake pads and brake discs). 3. Stable friction coefficient: Ordinary brake pads have immature friction materials, and a friction coefficient that is too high can lead to unsafe factors such as loss of control during braking, burning of the pads, and scratching of the brake discs. Even when the brake disc temperature reaches as high as 650 degrees, the friction coefficient of ceramic brake pads remains around 0.45-0.55, ensuring the vehicle maintains good braking performance.
