BRAKE: BRAKE SYSTEM: 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:
* Care must be taken to replace each part properly as it could affect the performance of the brake system and result in a driving hazard. Replace the parts with those having the same part number or equivalent.
* It is very important to keep parts and the work area clean when repairing the brake system.
* If the vehicle is equipped with a mobile communication system, refer to the precaution in the INTRODUCTION section Service Precautions.
* Care must be taken when using magnets as they 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 tube connections to prevent foreign matter such as dust or dirt from entering the tubes.
* Do not damage or deform the brake tubes when removing or installing them.
* When installing a brake tube grommet to the body, ensure that the brake tube passes through the center of the grommet.
* When installing a brake tube 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 tube to a plastic clamp, ensure that the brake tube is not loose or being pinched.
* Do not reuse a clip or plastic clamp removed from a flexible hose.
* After installing a brake tube 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.
* Follow these procedures when disconnecting the flexible hose and brake tube.





* Remove the clip.
* Hold the flexible hose with a wrench. Using SST, disconnect the brake tube without deforming the tube.
* Follow these procedures when connecting the flexible hose and brake tube.
* Hold the flexible hose with a wrench. Using SST, connect the brake tube without deforming the tube.
* Install a new clip.
* Connect the brake tube and 2-way:





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