CLEAN
WARNING
DO NOT use an oil solvent to clean the master cyl-
inder, wheel cylinder, or brake linings. Use a sol-
vent approved for cleaning of brake parts. DO
NOT permit oil or grease in the brake fluid or on
the brake linings. Oil and grease will cause dam-
age and leaks in the seals of a brake system. The
brakes will not operate correctly if oil, grease, or
brake fluid is on the brake linings.
Cleaning solvents can be flammable and toxic and
can cause skin irritation. When using cleaning
solvents, always follow the safety instructions of
the solvent manufacturer.
1.
DO NOT release brake lining dust from brake
linings into the air when brake drum is re-
moved.
2.
Use a solvent approved for cleaning of brake
parts to wet brake lining dust. Follow instruc-
tions and cautions of manufacturer for use of
solvent. If a solvent spray is used, spray at a
distance so that dust is not released into the
air.
3.
When brake lining dust is wet, clean parts. Put
any cloth or towels in a plastic bag or an air-
tight container while they are still wet. Put a
DANGEROUS FIBERS warning label on plas-
tic bag or airtight container.
