Make sure to replace each part properly. Improper installation or repair could
affect the performance of the brake system and cause a driving hazard.
NOTICE:
- It is very important to keep the brake system parts and the area clean
when repairing the brake system.
- Since the brake line is 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.

them.
- When installing a brake tube or flexible hose, make sure that it is
not twisted or bent.

- When installing a brake tube to a plastic clamp, make sure that the
brake tube is not loose or pinched.
- Do not reuse a clip removed from a flexible hose.

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.
