Lexus RX (RX 350L, RX450h) 2016-2023 Repair Manual: Brake Line

NOTICE:

• Since the brake lines are critical safety related parts, be sure to disassemble and inspect the components if a brake fluid leak is found. If any abnormalities are 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 allow brake fluid on any painted vehicle body surface. If brake fluid leaks onto any painted surface, immediately wash it off.
• When installing a grommet to the vehicle body, ensure that the brake line passes through the center of the grommet.
• Do not damage or deform the brake lines during the removal and installation procedures.
• When installing a brake line or flexible hose, ensure that they are free from twists or kinks.
• Do not deform the bracket or the vehicle body when connecting a brake line and flexible hose.
• If the metal end of a flexible hose does not fit into the groove on the bracket, twist the hose slightly to insert it.
• Flexible hoses must be kept free from shock absorber oil, grease, etc.
• When installing a brake line to a plastic clamp, ensure that the brake line is not loose or pinched.
• Do not reuse any clips or plastic clamps removed from a flexible hose.
• After installing a brake line or flexible hose, ensure that they do not interfere with any other components or the vehicle body.
