TROUBLESHOOTING PRECAUTION

NOTE:

Since the brake lines are classified as critical safety related parts, be sure to disassemble and 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 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.
Do not deform the bracket and the body when connecting a brake line and flexible hose.
When installing a brake tube grommet to the body, make sure that the brake line passes through the center of the grommet.
When installing a brake line or flexible hose, make sure that it is free from twists or bends.
If the cap 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, make sure that the brake line is not loose or pinched.
Do not reuse any clips or plastic clamps removed from a flexible hose or brake line.
After installing a brake line or flexible hose, make sure that it does 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.
