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 service area clean when repairing the brake system.
If the vehicle is equipped with a mobile communication system, refer to the precaution in the INTRODUCTION article.
Care must be taken when using magnets as they could affect the performance of the speed sensors.
Since the brake system is classified as one of the critical safety related parts, be sure to inspect 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 abnormal 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 shock 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 or rub on any other components.
Do not allow brake spill on 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 line:
1. Hold the flexible hose with a wrench and disconnect the brake tube with a union nut wrench without deforming the tube.
2. Remove the clip.
3. Install a new clip.
4. Connect the brake tube with a union nut wrench without deforming the tube.

Connect the brake tubes and brake tube way:
1. Support the way to prevent deformation of the brake tube and connect the brake tube to the way with a union nut wrench.
2. Support the way to prevent deformation to the brake tubes and install the bolt to attach the way to the body.
