REMOVAL ■ CAUTION ■ Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it out immediately and wash with water if it gets on a painted surface.

1.Remove the brake master cylinder cover and hood ledge cover LH. Refer to Exploded View.

2.Drain brake fluid. Refer to Draining.

3.Separate the brake fluid level switch harness connector.

4.Separate the brake tube from the master cylinder assembly with a flare nut wrench.
■ CAUTION ■
Never scratch the flare nut and the brake tube.

5.Depress the brake pedal several times to release the vacuum pressure from the brake booster. Then remove the master cylinder assembly.
■ CAUTION ■

- Never depress the brake pedal after the master cylinder assembly is removed.
- The piston of the master cylinder assembly is exposed. Never damage it when removing the master cylinder.
- The piston may drop off when pulled out strongly. Never hold the piston. Hold the cylinder body when handling the master cylinder assembly.

INSTALLATION
■ CAUTION ■
Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it out immediately and wash with water if it gets on a painted surface.
Note the following, and install in the reverse order of removal.

- Never depress the brake pedal after the master cylinder assembly is removed.
- Never reuse the O-ring.
- Apply polyglycol ether based lubricant 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 handling the master cylinder and 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 strongly. Never hold the piston. Hold the cylinder body when handling the master cylinder assembly.
- 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.
- Never allow foreign matter (e.g. dust) and oils other than brake fluid to enter the reservoir tank.
- Since brake fluid is susceptible to deterioration from moisture, discard brake fluid remaining in the container.
- After installation, perform the air bleeding. Refer to Bleeding Brake System.
  ■ CAUTION ■
  Never reuse drained brake fluid.
