- Certain components within the ABS system are not intended to be serviced
or repaired individually. Only those components with removal and installation
procedures should be serviced.
- Do not use rubber hoses or other parts not specifically specified for the
ABS system. When using repair kits, replace all parts included in the kit.
Partial or incorrect repair may lead to functional problems and require the
replacement of components.
- Lubricate rubber parts with clean, fresh brake fluid to ease assembly. Do
not use lubricated shop air to clean parts; damage to rubber components may
result.
- Use only DOT 3 brake fluid from an unopened container.
- If any hydraulic component or line is removed or replaced, it may be necessary
to bleed the entire system.
- A clean repair area is essential. Always clean the reservoir and cap thoroughly
before removing the cap. The slightest amount of dirt in the fluid may plug
an orifice and impair the system function. Perform repairs after components
have been thoroughly cleaned; use only denatured alcohol to clean components.
Do not allow ABS components to come into contact with any substance containing
mineral oil; this includes used shop rags.
- The Anti-Lock control unit is a microprocessor similar to other computer
units in the vehicle. Ensure that the ignition switch is OFF before
removing or installing controller harnesses. Avoid static electricity discharge
at or near the controller.
- If any arc welding is to be done on the vehicle, the ALCU connectors should
be disconnected before welding operations begin.
