BRAKE TUBE AND HOSE

ABS Actuator and Electric Unit Brake Pipe Connections for VQ40DE

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.
• When removing components, cover connections so that no dirt, dust, or other foreign matter gets in.
• Refill with new specified brake fluid. Refer to 

MA-12, "Fluids and Lubricants"

.

• Do not reuse drained brake fluid.
