6.1 Warnings and Notices

6.1.1 Warnings and Notices

ABS Component Handling Warning

Warning!

Warning: Certain components in the Anti-lock Brake
System (ABS) are not intended to be serviced
individually. Attempting to remove or disconnect certain
system components may result in personal injury and/or
improper system operation. Only those components with
approved removal and installation procedures should be
serviced.

Brake Dust Warning

Warning!

Warning: Avoid taking the following actions when you
service wheel brake parts:

–

Do not grind brake linings.

–

Do not sand brake linings.

–

Do not clean wheel brake parts with a dry brush or
with compressed air.

Warning!

Warning: Some models or aftermarket brake parts may
contain fibers which can become airborne in dust.
Breathing dust with fibers may cause serious bodily
harm. Use a water-dampened cloth in order to remove
any dust on brake parts. Equipment is available
commercially in order to perform this washing function.
These wet methods prevent fibers from becoming
airborne.

Brake Fluid Warning

Warning!

Warning: Do not use fluid from an open container that
may be contaminated with water. Incorrect or
contaminated fluid could result in system failure, loss of
vehicle control and personal injury.

Brake Fluid Irritant Warning

Warning!

Warning: Brake fluid may be irritating to the skin or eyes.
In case of contact, take the following actions:

–

Eye contact--rinse eyes thoroughly with water.

–

Skin contact--wash skin with soap and water.

Brake Pipe Replacement Warning

Warning!

Warning: Carefully route and retain replacement brake
pipes. Always use the correct fasteners and in the
original location for replacement brake pipes. Failure to
properly route and retain brake pipes may cause
damage to the brake pipes and brake system resulting
in personal injury.

Adding Fluid to the Brake System Notice

Note

Notice: When adding fluid to the brake master cylinder
reservoir, use DOT-4 brake fluid from a clean, sealed
brake fluid container. The use of any type of fluid other
than the recommended type of brake fluid may cause
contamination which could result in damage to the
internal rubber seals and/or rubber linings of hydraulic
brake system components.

Brake Caliper Notice

Note

Notice: Support the caliper with a piece of wire to prevent
damage to the brake line.
