Begin the brake master cylinder replacement by draining brake fluid before cleaning all fluid that contacts painted surfaces with suitable methods. The battery negative terminal must be separated while the air cleaner assembly with hose receives removal before proceeding to detach the cowl top panel sub-assembly's outer front. Special Service Tool: 09023-00101 enables the removal of 2 brake tubes from the brake master cylinder assembly by disconnecting the brake master cylinder reservoir hose with the clip sliding mechanism before unscrewing both brake master cylinder nuts. The brake master cylinder installation requires two nut fastening with a torque of 13 Nm (130 kgf-cm, 9 ft. lbs.) followed by reconnecting the brake master cylinder reservoir hose using the clip and applying Special Service Tool: 09023-00101 to join the two brake tubes to the master cylinder with 15 Nm (155 kgf-cm, 11 ft. lbs. torque). The install procedure includes reattaching the air cleaner assembly with hose followed by a brake fluid fill in the reservoir then performing brake master cylinder, brake line, and brake actuator with VSC bleeding. The first step of check includes inspecting brake fluid reservoir levels while looking for leakages. Next install both cowl top panel sub-assembly and front outer panels and measure brake pedal height before testing the brake actuator with the intelligent tester.
