Toyota 4Runner: Brake Line

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.
• 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, make sure 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, make sure that the brake tube is not loose or pinched.
• Do not reuse a clip removed from a flexible hose.
• After installing a brake tube or flexible hose, make sure that it does 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. Text in Illustration
