SECTION 12: BRAKE AND AIR SYSTEM
22
DOB 2490-2789 | X3-45 Commuter PA1605 Maintenance Manual (Final Version – Rev.2 April 2016)
WARNING
NEVER use compressed air or dry brushing to
clean brake parts or assemblies. OSHA
recommends that you use cylinders that
enclose the brake. These cylinders have
vacuums with high efficiency (HEPA (Health
and Environment Protection Agency)) filters
and workmans’ arm sleeves. But, if such
equipment is not available, carefully clean
parts and assemblies in the open air.
Clean brake parts and assemblies in the open
air. During disassembly, carefully place all
parts on the floor to avoid getting dust into the
air. Use an industrial vacuum cleaner with a
HEPA filter system to clean dust from the
brake drums, backing plates and other brake
parts. After using the vacuum, remove any
remaining dust with a rag soaked in water and
wrung until nearly dry.
If you must grind or machine brake linings,
take additional precautions because contact
with fiber dust is higher during these
operations. In addition to wearing an
approved respirator, do such work in an area
with exhaust ventilation.
When cleaning the work area, NEVER use
compressed air or dry sweeping to clean the
work area. Use an industrial vacuum with a
HEPA filter and rags soaked in water and
wrung until nearly dry. Dispose of used rags
with care to avoid getting dust into the air. Use
an approved respirator when emptying
vacuum cleaners and handling used rags.
Wash your hands before eating, drinking or
smoking. Do not wear your work clothes
home. Vacuum your work clothes after use
and then launder them separately, without
shaking, to prevent fiber dust from getting into
the air.
Material safety data sheets on this product, as
required by OSHA, are available from
Rockwell and Knorr-Bremse.
WARNING
Whenever possible, work on brakes in a
separate area away from other operations.
Always wear a respirator approved by NIOSH
(National Institute of Occupational Safety and
Health) or MSHA (Mine Safety and Health
Administration) during all brake service
procedures. Wear the respirator from removal
of the wheels through assembly.
