Brake System: Precaution

NOTE:

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 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.
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 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 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.
Disconnect and connect the flexible hose and brake tube:
1. Remove the clip.
2. Hold the flexible hose with a wrench and disconnect the brake tube with a union nut wrench without deforming the tube.
3. Connect the brake tube with a union nut wrench without deforming the tube.
4. Install a new clip.
