Brake Line: Precaution: Precaution

NOTE:
  • Since the brake lines are classified as critical safety related parts, be sure to disassemble and inspect the components if any brake fluid leaks are found. If any abnormality is found, replace the component with a new one.
  • When removing brake system components, cover the brake line connections to prevent foreign matter such as dust or dirt from entering the lines.
  • 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 clean it off.
  • Do not damage or deform the brake lines when removing and installing them.
  • When installing a brake tube or flexible hose, ensure that they are free from twists or bends.
  • Do not deform the bracket or the body when connecting a brake line and flexible hose.
  • 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 tube to a plastic clamp, ensure that the brake tube is not loose or pinched.
  • Do not reuse any clips or plastic clamps removed from a flexible hose.
  • After installing a brake tube or flexible hose, ensure that they do not interfere with any other components.
  • When disconnecting and connecting a flexible hose and brake tube:
