• Q: How to remove and install the Brake Master Cylinder on 2007 Toyota Sequoia?

  A: The procedure to remove the Brake Master Cylinder starts with draining fluid by syringe after which any brake fluid contact with painted surfaces requires immediate cleaning. You need to detach the master cylinder pressure sensor connector along with the brake fluid level warning switch connector and wire harness by implementing a clip remover to separate its components from the wire harness bracket. Remove the 2 brake lines from the master cylinder after using Special Service Tool: 09023-38201 to achieve a torque of 19.5 Nm (195 kgf-cm, 14 ft. lbs.). Uninstall the brake master cylinder by first removing both its retaining nuts along with the wire harness bracket then torquing to 25 Nm but using 250 kgf-cm (18 feet lbs.). Finally, lift the master cylinder off the brake booster. Begin by running the installation in reverse order followed by brake fluid addition to the reservoir then bleed the brake system while checking for any fluid leaks. The replacement of master cylinder assemblies or master cylinder pressure sensors requires zero point sensor calibration of steering angle along with master cylinder pressure and yaw rate and deceleration sensors.
