INSTALL BRAKE ACTUATOR ASSEMBLY
1. Install the brake actuator assembly to the brake actuator bracket assembly with the 3 bolts.
  Torque: 5.4 N*m (55 kgf*cm, 48 in.*lbf)
  NOTE:
  - Do not remove the hole plugs before installing a new brake actuator assembly because the brake actuator is filled with brake fluid.
  - Do not carry the brake actuator assembly by the connector.
  - Tighten the 3 bolts in the order shown in the illustration.
