After replacing the brake actuator assembly, make sure to perform update ECU security key.
After performing the update ECU security key procedure, make sure to perform the initialization procedure for when the cable has been disconnected and reconnected to the negative (-) auxiliary battery terminal.
The parking brake indicator light blinks (red) when the ignition switch is turned to ON after replacing the brake actuator assembly. Operate the electric parking brake switch assembly to turn off the parking brake indicator light.

2.INSTALL BRAKE ACTUATOR ASSEMBLY
Temporarily install the brake actuator assembly to the brake actuator bracket assembly with the 3 bolts.
Tighten the 3 bolts in the order shown in the illustration.
Do not remove the hole plugs of a new brake actuator assembly before connecting the brake tubes because the brake actuator assembly is filled with brake fluid.
Do not hold the brake actuator assembly by the connector.
Do not drop the brake actuator assembly when carrying it.
Make sure that the brake actuator assembly is in full contact with the brake actuator bracket assembly.
3.INSTALL BRAKE ACTUATOR WITH BRACKET
Temporarily install the brake actuator with bracket to the vehicle body with the 2 bolts and nut.
Do not kink or damage the brake lines.
Do not allow any foreign matter such as dirt or dust to enter the brake lines from the connecting parts.
Be careful not to allow any brake fluid to enter the connector.
Do not hold the brake actuator assembly by the connector.
Do not drop the brake actuator with bracket when carrying it.
Install the brake actuator with bracket while avoiding the brake lines.
Fully tighten the 2 bolts and nut in the order shown in the illustration.
Install a new brake tube clamp with the bolt.
Engage the 5 clamps to connect the brake lines to the brake tube clamp.
Do not kink or damage the brake lines.

| *c | To Front Wheel Cylinder Assembly RH |
| *d | To Rear Wheel Cylinder Assembly LH |
| *e | To Rear Wheel Cylinder Assembly RH |
| *f | To Front Wheel Cylinder Assembly LH |
Temporarily install each brake line to the correct position on the brake actuator assembly as shown in the illustration.
Do not kink or damage the brake line.
Do not allow any foreign matter such as dirt or dust to enter the brake line from the connecting parts.
| *a | Torque Wrench Fulcrum Length |
| *b | Union Nut Wrench |
Using a union nut wrench, connect the 6 brake lines to the brake actuator assembly.
Do not kink or damage the brake lines.
Do not allow the brake lines to twist or interfere with other parts or the vehicle body during tightening.
Do not allow any foreign matter such as dirt or dust to enter the brake lines from the connecting parts.
Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
When using a union nut wrench (fulcrum length of 22 mm (0.866 in.)) + torque wrench (fulcrum length of 162 mm (6.38 in.)):
(A): 13.4 N*m (137 kgf*cm, 10 ft.*lbf)
When using a union nut wrench (fulcrum length of 20 mm (0.787 in.)) + torque wrench (fulcrum length of 162 mm (6.38 in.)):
(B): 17.4 N*m (177 kgf*cm, 13 ft.*lbf)
