WARNING: This page is about a different car, the 2011 Lexus IS 350 and 2011 Lexus IS 250. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • Care must be taken to replace each part properly as it could affect the performance of the brake system and result in a driving hazard. Replace the parts with those having the same part number or equivalent.
  • It is very important to keep parts and the service area clean when repairing the brake system.
  • If the vehicle is equipped with a mobile communication system, refer to the precaution in the INTRODUCTION section.
  • Care must be taken when using magnets as they could affect the performance of the speed sensors.
  • Since the brake system is classified as one of the critical safety related parts, be sure to 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 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 grommet to the body, ensure that the brake tube passes through the center of the grommet.
  • When installing a brake tube or flexible hose, ensure that they are free from twisting or abnormal bending.
  • If the cap 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 shock 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 or plastic clamp removed from a flexible hose.
  • After installing a brake tube and flexible hose, ensure that they do not interfere or rub on any other components.
  • Do not allow brake spill on adhere to any painted surface such as the vehicle body. If brake fluid leaks onto any painted surface, immediately wash it off.
  • Disconnect and connect the flexible hose and brake line:
