NOTICE:

Since the brake lines are critical safety related parts, be sure to disassemble and inspect the components if a brake fluid leak is found. If any abnormalities are 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 during the removal and installation procedures.
When installing a grommet to the vehicle body, ensure that the brake line passes through the center of the grommet.
Do not deform the bracket or the body when connecting a brake line and flexible hose.
When installing a brake line or flexible hose, ensure that they are free from twists or kinks.
If the metal end of a 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 line to a plastic clamp, ensure that the brake line is not loose or pinched.
Do not reuse any clips or plastic clamps removed from a flexible hose.
After installing a brake line or flexible hose, ensure that they do not interfere with any other components or vehicle body.
Do not allow brake fluid on any painted vehicle body surface. If brake fluid leaks onto any painted surface, immediately wash it off.
