General Safety Information

Some brake linings contain non-asbestos ﬁbers, the

long term effects of which are unknown. Some older

original equipment brake linings contain asbestos

ﬁbers, a cancer and lung disease hazard. Caution

should be exercised in handling both asbestos and

non-asbestos materials.

Most recently manufactured brake linings no longer con-

tain asbestos ﬁbers. In place of asbestos, these linings

contain a variety of ingredients, including glass ﬁbers,

mineral wool, aramid ﬁbers, ceramic ﬁbers, and carbon

ﬁbers. At present, OSHA does not speciﬁcally regulate

these non-asbestos ﬁbers, except as maintenance dust.

Medical experts do not agree about potential long term

risks from working with and inhaling non-asbestos ﬁbers.

Some experts think that long term exposure to certain

non-asbestos ﬁbers could cause diseases of the lung,

including pneumoconiosis, ﬁbrosis, and cancer. There-

fore it is recommended that workers use caution to avoid

spreading and breathing dust when working on brakes

that contain non-asbestos ﬁbers.

Personal injury hazard. Never disconnect an air sys-

tem component unless all system pressure has been

depleted. Failure to deplete system pressure before

disconnecting hoses or components may result in

them separating violently and causing serious bodily

injury or death.

Observe the following precautions when working with

brakes and brake lining material:

1 Whenever possible, work on brakes in an area sep-

arate from other operations.

2 Always wear a respirator approved by NIOSH or

MSHA during all brake service procedures. Wear

the respirator during removal of wheels and through-

out the assembly.

3 Never use compressed air or dry brushing to clean

brake parts or assemblies. OSHA recommends that

brake enclosures be used. These enclosures have

vacuums with a High Efﬁciency Particulate Air

(HEPA) ﬁlter and worker arm sleeves. If such equip-

ment is not available, carefully clean brake parts

and assemblies in the open air.
