3.INSTALL BRAKE ACTUATOR ASSEMBLY
Install the brake actuator assembly to the brake actuator bracket assembly with 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.
4.INSTALL BRAKE ACTUATOR WITH BRACKET
Temporarily install the brake actuator with bracket 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.
Hold the brake actuator with bracket by the brake actuator assembly.
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.
5.CONNECT BRAKE LINE
| *a | From 1st Chamber of Brake Booster with Master Cylinder Assembly |
| *b | From 2nd Chamber of Brake Booster with Master Cylinder Assembly |
Temporarily tighten the 2 brake lines to the correct position on the brake actuator assembly as shown in the illustration.
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.
| *a | Torque Wrench Fulcrum Length |
| *b | Union Nut Wrench |
Using a union nut wrench, fully tighten the 2 brake lines.

Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
When using a union nut wrench (fulcrum length of 20 mm (0.787 in.)) + torque wrench (fulcrum length of 162 mm (6.38 in.)):
17.4 N*m (177 kgf*cm, 13 ft.*lbf)
| *a | To Front Disc Brake Cylinder Assembly RH |
| *b | To Rear Disc Brake Cylinder Assembly LH |
| *c | To Rear Disc Brake Cylinder Assembly RH |
| *d | To Front Disc Brake Cylinder Assembly LH |
Temporarily tighten the 4 brake lines to the correct position on the brake actuator assembly as shown in the illustration.
Do not kink or damage the brake lines.
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, fully tighten the 4 brake lines.
Do not kink or damage the brake lines.
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.)):
13.4 N*m (137 kgf*cm, 10 ft.*lbf)
Install the brake lines with the 2 bolts.
