Before installing the brake actuator together with its bracket you must keep the hole plug inside until completing the brake tube connection because new brake actuators contain brake fluid. Three nuts require a 19 Nm (194 kgf-cm, 14 ft-lbf) torque for installation of the actuator with bracket. It is essential to tighten the nuts in alphabetical order yet maintain proper care for the brake tubes and to avoid dropping the actuator with a mandatory replacement if it does get dropped. Begin by adding the brake tube clamp to the bracket; then correctly position all brake lines on the actuator before connecting them with a 10 mm union nut wrench at 15 Nm torque (155 kgf-cm, 11 ft-lbf) wrench-free or 14 Nm (145 kgf-cm, 10 ft-lbf) with wrench support while maintaining a 300 mm (11.8 in.) torque wrench fulcrum at 90 degrees from the union nut wrench. The procedure starts by attaching the connector then lowering the lock lever while performing fluid addition to the reservoir followed by bleeding air through the brake master cylinder and brake lines and ABS and traction actuator assembly before checking the fluid level and inspecting for leaks. The assembly process includes adding the air cleaner case sub-assembly for both 2AR-FE and 2GR-FE engines. Prior to checking the ABS and traction actuator assembly with Techstream you must connect the cable to the negative battery terminal.

Remove the 3 cushions from the actuator.

Using Special Service Tool: 09023-00101, disconnect the 6 brake lines from the actuator, placing tags or marks to identify the installation locations of each line.

A union nut wrench (10 mm).

Ensure not to remove the hole plug before connecting the brake tube, as new actuators are filled with brake fluid.
