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:

    The freedom of indifference, the indifference of freedom, the will dust in the dust of its object, the act a handful of sand let fall—these were some of the shapes he had sighted, sunset landfall after many days.
    Samuel Beckett (1906–1989)
