Removal and installation


CAUTION:
Never disassemble the electrically-driven intelligent brake unit other than reservoir cap, oil stainer, master cylinder pressure sensor1 and master cylinder pressure sensor2.

REMOVAL


CAUTION:
- 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. For brake component parts, never wash them with water.
- Never depress brake pedal.while removing the brake tube. If this is not complied with, brake fluid may splash.

INSTALLATION

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. For brake component parts, never wash them with water.
- Never depress brake pedal.while removing the brake tube. If this is not complied with, brake fluid may splash.
- Be careful not to damage electrically-driven intelligent brake unit stud bolt threads. If electrically-driven intelligent brake unit is tilted during installation, the dash panel may damage the threads.
- Never deform or bend the brake tubes when installing the electrically-driven intelligent brake unit.
- Never reuse clevis pin. Adjustments.
- Temporarily tighten the brake tube flare nut to the electrically-driven intelligent brake unit by hand. Then tighten it to the specified torque with a crowfoot and torque wrench.
- Perform the air bleeding. Service and Repair.
- Check each item of brake pedal. Adjust it if the measurement value is not the standard. Adjustments.
- Perform stroke sensor 0 point learning when electrically-driven intelligent brake unit is removed and installed, or replaced. Work Procedure.
