Disc Brake - Brake Dust

Brake Dust

When braking force is applied, the act of abrasive friction between the brake pad and the rotor wears both the rotor and pad away. The "brake dust" that is seen deposited on wheels, calipers and other braking system components consists mostly of rotor material. Brake dust can damage the finish of most wheels if not washed off. Generally brake pad that aggressively abrades more rotor material away, such as metallic pads, will create more brake dust.

Famous quotes containing the word dust:

    “And then finally there’s your grandmother
    Sweeping the dust of the nineteenth century
    Into the twentieth, and your grandfather plucking
    A straw out of the broom to pick his teeth.”
    —Charles Simic (b. 1938)
