Title: BRAKE SYSTEM (OTHER): BRAKE LINE: PRECAUTION (2008 LX570)

PRECAUTION

CAUTION:

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 work 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.
  • 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 brake tube or flexible hose, ensure that it is not twisted or bent.
  • If the fitting 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 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 removed from a flexible hose.
  • After installing a brake tube and flexible hose, ensure that they do 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.


  • Follow these procedures when disconnecting the flexible hose and brake tube.
    1. Hold the flexible hose with a wrench. Using a union nut wrench, disconnect the brake tube without deforming the tube.
    2. Remove the clip.
  • Follow these procedures when connecting the flexible hose and brake tube.
    1. Install a new clip.
    2. Hold the flexible hose with a wrench. Using a union nut wrench, connect the brake tube without deforming the tube.
  • Follow these procedures when connecting the brake tube and 2-way.

    1. Connect the brake tubes to the 2-way and tighten the flare nuts of the brake tubes by hand.
    2. Support the 2-way to prevent deformation to the brake tubes and install the bolt to fix the 2-way to the frame.
    3. Support the 2-way to prevent deformation to the brake tubes and tighten the flare nuts of the brake tubes to the torque specification with a union nut wrench.
