3. Disconnect the brake hose (1) from brake tube (2) at the flarenut (A) using a suitable tool and remove the lock plate (3).
4. Remove the union bolt (A) and remove brake hose from caliper assembly. Discard the copper sealing washers.
• Protrusions (B)
CAUTION:
Do not reuse the copper sealing washers.
5. Remove the brake hose.
INSTALLATION
CAUTION:
• All brake hoses and brake tubes must be free fr om excessive bending, twisting and pulling.
• Make sure that there is no interference with othe r parts when turning steering both clockwise and
counterclockwise.
• Brake tubes and brake hoses are an important safety part. Always disassemble the parts and
retighten their fittings if a brake fluid leak is detect ed. Replace applicable part with a new one, if dam-
aged part is detected.
• 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.
• Refill with new brake fluid “DOT 3”.
• Do not reuse drained brake fluid.
1. Assemble the union bolt and new copper sealing washers on the brake hose. CAUTION:
Do not reuse the copper sealing washers.
2. Install brake hose by aligning the brake hose with the protrusion (B) on brake caliper assembly as shown. Tighten union bolt (A)
to the specified torque. Refer to BR-20, "FRONT : Exploded
View".

CAUTION:
• All hoses and piping (tubes) must be free from excessive bending, twisting and pulling.
• Make sure there is no interference with other part s when turning steering both clockwise and coun-
terclockwise.
• 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.
• Do not reuse drained brake fluid.
• After installation of the ABS actuator and electric unit (control unit), refill brake system with new
brake fluid. Then bleed the ai r from the system. Refer to BR-14, "Bleeding Brake System"
.

INSTALLATION
CAUTION:
Do not allow foreign matte r (e.g., dust) and oils other than brake fluid to enter the reservoir tank.
1. Assemble the union bolt (A) and the copper sealing washers (1) to the brake hose and install it as an assembly to the brake cali-
per. Align the brake hose L-pin by aligning it with the brake cali-
per hole, and tighten the union bolt (A) to the specified torque.
CAUTION:
Do not reuse copper sealing washers.
2. Install the brake pipe to the brake hose, temporarily tighten the flare nut by hand until it does not rotate further, and attach the
brake hose to the bracket with the lock plate.
CAUTION:
Check that the brake hoses and pipes are not bent or
twisted.
3. Connect brake hose (1) to brake tube (2). Tighten flare nut (A) to specification and secure to the bracket with lock plate (3).
4. Refill with new brake fluid and perform air bleeding. Refer to BR-
14, "Bleeding Brake System".
CAUTION:
Do not reuse drained brake fluid.
5. Install the wheel and tire. Refer to WT-60, "Road Wheel"
