Note the following, and install in the reverse order of removal.

• Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it off immediately and wash with water if it gets on a painted surface.
• Never depress the brake pedal. Brake fluid may splash while removing the brake tube.
• Never depress the brake pedal after the master cylinder assembly is removed.
• Apply silicone grease to the brake booster [see (A) in the figure] when installing the master cylinder assembly to the brake booster.

• The piston of the master cylinder assembly is exposed. Never damage it when removing the master cylinder.
• Check that no dirt and dust are present on the piston before installation. Clean it with new brake fluid if necessary.
• The piston may drop off when pulled out strongly. Never hold the piston. Hold the cylinder body when handling the master cylinder assembly.
• Never reuse the O-ring.
• Temporarily tighten the brake tube flare nut to the master cylinder assembly by hand. Then tighten it to the specified torque with a flare nut crowfoot and torque wrench. Refer to Exploded View .
  CAUTION: Never scratch the flare nut and the brake tube.
• Refill with new brake fluid and perform the air bleeding. Refer to Bleeding Brake System .
• Perform inspection after installation. Refer to Inspection .
