Brakes and Traction Control: Service Precautions

BRAKE: BRAKE SYSTEM: PRECAUTION

PRECAUTION
CAUTION: When the brake caliper is removed from the brake disc, do not start the hybrid system. If the hybrid system is started, the brake fluid pressure may increase.
Perform the service after turning the power switch OFF, and checking that the "READY" indicator turns off.
NOTICE:
- Part replacement in the brake system must be done carefully to ensure proper performance and avoid driving hazards. Replace the parts with those having the same part number or equivalent.
- It is very important to keep both the parts and the area clean when repairing the brake system.
- If the vehicle is equipped with a mobile communication system, refer to the precaution.
- Care must be taken when using magnets as it could affect the performance of the speed sensors.
- Since the brake line is classified as one of the critical safety related parts, be sure to disassemble the components if a brake fluid leak is found. If any abnormality is found, replace the component with a new one.
- When removing brake components, cover the brake line connections to prevent foreign matter such as dust or dirt from entering the lines.
- Do not damage or deform the brake lines when removing or installing them.
- When installing a grommet to the body, ensure that the brake line passes through the center of the grommet.
- When installing a brake line or flexible hose, ensure that they are free from twisting or bending.
- If the cap of the flexible hose does not match the groove on the bracket, twist the hose slightly to insert it.
- Flexible hoses must be free from absorber oil, grease, etc.
- When installing a brake line to a plastic clamp, ensure that the brake line is not loose or being pinched.
- Do not reuse a clip or plastic clamp removed from a flexible hose.
- After installing a brake line and flexible hose, ensure that they do not interfere with any other components.
- Do not allow brake fluid to adhere to any painted surface such as the vehicle body. If brake fluid leaks onto any painted surface, immediately wash it off.
- Separate and connect the flexible hose and brake line.





1. Remove the clip.
2. Hold the flexible hose with a wrench and disconnect the brake line with a union nut wrench without deforming the line.
3. Connect the brake line with a union nut wrench without deforming the line.
4. Install a new clip.
- Connect the brake line and way.





1. Support the way to prevent deformation to the brake line and connect the brake line to the way with a union nut wrench.
2. Support the way to prevent deformation to the brake line and install the bolt to fix the way to the body.
