ELECTRICALLY-DRIVEN INTELLIGENT BRAKE UNIT

Removal and installation


CAUTION:
Never disassemble the electrically-driven intelligent brake unit.

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.
1.Perform inspection before removal. Refer to "Inspection and Adjustment" Inspection.
2.Turn the power switch OFF.

6.Drain brake fluid. Refer to "Draining" Draining.
7.Disconnect the brake fluid level switch harness connector.
8.Remove reservoir tank and hose.
9.Remove reservoir tank bracket.
10.Disconnect the electrically-driven intelligent brake unit harness connector.
11.Disconnect the master cylinder pressure sensor1 and master cylinder pressure sensor2 harness connector.
12.Separate the brake tube from electrically-driven intelligent brake unit with a flare nut wrench.

CAUTION:
To prevent damage to the parts, never scratch the flare nut and the brake tube.





13.Remove snap pin (1) and clevis pin (2). Refer to "Removal and Installation" Removal And Installation.
14.Remove nuts on electrically-driven intelligent brake unit and brake pedal assembly.

CAUTION:
To prevent damage to the parts, hold the electrically-driven intelligent brake unit so as to avoid dropping out.
15.Remove electrically-driven intelligent brake unit.

CAUTION:
To prevent damage to the parts, never deform or bend the brake tubes.
16.Remove master cylinder pressure sensor1 and master cylinder pressure sensor2.
17.Perform inspection after removal. Refer to "Inspection and Adjustment" Inspection.

INSTALLATION


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.
Note the following, and install in the reverse order of removal.
- 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.
- 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.
- Never reuse the clevis pin.
- Perform the air bleeding. Refer to "Bleeding Brake System" Service and Repair.
- Check each item of brake pedal. Adjust it if the measurement value is not the standard. Refer to "Inspection and Adjustment" Adjustments.
- Perform stroke sensor 0 point learning when electrically-driven intelligent brake unit is removed and installed, or replaced. Refer to "Work Procedure" Work Procedure.
