BRAKE TUBE AND HOSE

Hydraulic Circuit

INFOID:0000000009466591

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-15, "FOR USA AND CANADA : Fluids and Lubri-

cants"

 (for United States and Canada) or  

MA-15, "FOR USA AND CANADA : Fluids and Lubricants"

(for Mexico).

• Do not reuse drained brake fluid.

Brake tubes and hoses are important safety parts. Always disassemble the parts and retighten their fit-

tings if a brake fluid leak is detected. Replace applicable part with a new one, if a damaged part is

detected.
1. Check brake lines (tubes and hoses), and connections for fluid leaks, damage, twist, deformation, contact

with other parts, and loose connections. Replace any parts as necessary. Refer to 

BR-20, "Hydraulic Cir-

cuit"

.

2. While depressing brake pedal under a force of 785 N (80 kg, 177 lb) with engine running for approximately

5 seconds, check each part for fluid leaks.
