INTRODUTION

m

WARNING: Never operate the vehicle if

there is any brake problem, no matter

how minor. Brakes can fail causing injury

or death.

Non-Asbestos Fibers Warning

FIG. 1:

m

WARNING: The following procedures for

servicing brakes are recommended to

reduce exposure to non-asbestos fiber

dust, a cancer and lung disease hazard.

Material Safety Data Sheets are available

from AxleTech.

Hazard Summary

Most recently manufactured brake linings do not

contain asbestos fibers. These brake linings may

contain one or more of a variety of ingredients,

including glass fibers, mineral wool, aramid fibers,

ceramic fibers and silica that can present health risks if

inhaled. Scientists disagree on the extent of the risks

from exposure to these substances. Nonetheless,

exposure to silica dust can cause silicosis, a

non-cancerous lung disease. Silicosis gradually

reduces lung capacity and efficiency and can result in

serious breathing difficulty. Some scientists believe

other types of non-asbestos fibers, when inhaled, can

cause similar diseases of the lung. In addition, silica

dust and ceramic fiber dust are known to the State of

California to cause lung cancer. U.S. and international

agencies have also determined that dust from mineral

wool, ceramic fibers and silica are potential causes of

cancer.

Accordingly, workers must use caution to avoid creating

and breathing dust when servicing brakes. Specific

recommended work practices for reducing exposure to

non-asbestos dust follow. Consult your employer for

more details.
