The installation process for the brake master cylinder starts by keeping the tip of the master cylinder oriented downward to avoid piston loss while cleaning the piston before applying lithium soap base glycol grease to its outer circumference contact surfaces. Attach the master cylinder to the booster with two nuts where the torque should be set at 12.5 Nm (127 kgf-cm, 9 ft-lbf). Insert and torque the two
Brake Lines designated B to the master cylinder by utilizing Special Service Tool: 09023-00101 with torques at 15.2 Nm (155 kgf-cm, 11 ft-lbf) and 14 Nm (144 kgf-cm, 10 ft-lbf) delivered by a torque wrench with a 30 cm (11.81 in.) fulcrum length. The master cylinder receives connector A from the brake fluid level warning switch then the fluid reservoir is filled before air bleeds out of the brake master cylinder along with the brake lines and ABS and traction actuator assembly. Inspection of the brake fluid reservoir and search for any brake fluid leaks is necessary. The installation requires proper methods to place the air cleaner case sub-assembly for 2AZ-FE or the air cleaner case for 2GR-FE.
