< REMOVAL AND INSTALLATION >

BRAKE PIPING

CAUTION:

• All hoses and piping (tubes) must be free from excessive bending, twisting and pulling.

• Make sure there is no interference with other parts.

• 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.

• Do not spill or splash brake fluid on painted surfaces. Brake fluid may damage paint. 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.

• 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 air from the system. Refer to

BR-17, "Bleeding Brake System"

REMOVAL

CAUTION:

• Do not spill or splash brake fluid on painted surfaces. Brake fluid may damage paint. If brake fluid is

splashed on painted areas, wash it away with water immediately.

• Do not scratch the piston of master cylinder when installing/removing because the piston is

exposed. Check for any dust on the piston, and wash with brake fluid if needed.

• Hold the master cylinder body when handing the master cylinder assembly. Do not hold the piston

because the piston might become detached if pulled strongly.

• Refill the reservoir tank with new brake fluid “DOT 3”.

• Do not reuse drained brake fluid.

• Do not reuse master cylinder O-ring.

NOTE:

When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spill-

ing.
1. Partially drain brake fluid. Refer to

BR-17, "Drain and Refill"

2. Disconnect the harness connector from the brake fluid level switch.
3. Remove air duct and air cleaner case. Refer to
