• Q: How to service and repair the brake master cylinder on 2007 Toyota Highlander?

  A: Service and repair of the brake master cylinder starts with removing the front suspension sub-assembly upper center through the removal of 4 nuts and the front suspension brace sub-assembly upper center. The service requires air cleaner assembly removal for 2AZ-FE engines while 1MZ-FE engines need air cleaner cap sub-assembly combined with the air cleaner filter element sub-assembly along with the air cleaner case. Remove the brake fluid while paying close attention to clearing off any brake fluid contact with painted surfaces right away. The Professional Service Tool: 09023-00101 assists in removing the brake master cylinder sub-assembly through disconnecting the 2 brake tubes followed by disconnecting and removing the brake fluid level warning switch connector and checking valve bracket with its accompanying 2 nuts. Begin installation by attaching the brake master cylinder sub-assembly with the check valve bracket using 2 nuts and torquing them to 13 Nm (130 kgf-cm, 9 ft. lbs.) and then apply Special Service Tool: 09023-00101 to connect the 2 brake tubes with torques set at 15 Nm (155 kgf-cm, 11 ft. lbs.). Finally, reconnect the brake fluid level warning switch connector. After filling the brake fluid reservoir complete the bleeding operations starting with the master cylinder followed by the brake line then ending with the brake actuator assembly. The installation process for both the 2AZ-FE and 1MZ-FE engines requires reinstallation of the air cleaner assembly and the combination of air cleaner case along with air cleaner filter element sub-assembly and air cleaner cap sub-assembly. The front suspension brace sub-assembly upper center requires installation using 4 nuts which need torquing up to 80 Nm (816 kgf-cm, 59 ft. lbs.) while inspecting brake fluid leaks followed by verifying the reservoir fluid level.
