CAUTION:

• All hoses and piping (tubes) must be free from excessive bending, twisting and pulling.
• Make sure there is no interference with other parts when turning the steering wheel both clockwise and counterclockwise.
• The brake piping is an important safety part. If a brake fluid leak is detected, always disassemble the parts. Replace applicable part with a new one, if necessary.
• Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is splashed on painted areas, wash it away with water immediately.
• Do not bend or twist brake hose sharply, or strongly pull it.
