wheel brake parts with a dry brush or with compressed air. Some models
or aftermarket brake parts may contain asbestos fibers which can become
airborne in dust. Breathing dust with asbestos fibers may cause serious
bodily harm. Use a water-dampened cloth in order to remove any dust on
brake parts. Equipment is available commercially in order to perform this
washing function. These wet methods prevent fibers from becoming
airborne.
