WARNING
Use only fresh, uncontaminated D.O.T. 4 fluid. Cans of
fluid that have been opened may have been contami-
nated by moisture in the air or dirt. Use of contaminated
brake fluid may adversely affect braking ability and lead
to brake failure which could result in death or serious
injury

WARNING
1
WARNING
Use only new copper crush banjo washers (See Parts
Catalog for Part No.) with D.O.T. 4 brake fluid. Earlier sil-
ver banjo washers are not compatible with D.O.T. 4 fluid
and will not seal properly over time. Failure to comply
may adversely affect braking ability and lead to brake
failure which could result in death or serious injury.

WARNING

WARNING
Use denatured alcohol to clean brake system compo-
nents. Do not use mineral-based solvents (such as gaso-
line or paint thinner), which will deteriorate rubber parts
even after assembly. Deterioration of these components
can cause brake failure, which could result in death or
serious injury. (00291a)

WARNING
After repairing the brake system, test brakes at low
speed. If brakes are not operating properly, testing at
high speeds can cause loss of control, which could
result in death or serious injury. (00289a)
CAUTION
D.O.T. 4 brake fluid will damage painted and molded-in
color surfaces it comes in contact with. Always use cau-
tion and protect surfaces from spills whenever brake
work is performed. Failure to comply can result in cos-
metic damage. (00239a)
