• Q: How to install the vacuum brake booster on 2009 Toyota Matrix?

  A: The brake master cylinder push rod clevis requires temporary tightening with the lock nut and clevis while attaching to the brake booster assembly for adjusting brake pedal height before completing lock nut torque. The installation process starts with fitting a new brake booster gasket to the brake booster assembly and proceeding to attach the assembly to the body through 4 nuts tightened at 13 Nm (132 kgf-cm, 10 ft-lbf) while avoiding contact with brake or fuel lines along with clamping down the brake lines. You must install the No. 5 front brake tube to the body before engaging the grommet and connecting the No. 5 front brake tube to the front brake flexible hose LH using a 10 mm union nut wrench that requires 15 Nm (155 kgf-cm, 11 ft-lbf) torque without a wrench but only reaches 14 Nm (143 kgf-cm, 10 ft-lbf) torque with a wrench while maintaining a 250 mm (9.84 in.) torque wrench fulcrum length that remains parallel to the union nut wrench. Add a new check valve grommet onto the brake booster assembly followed by putting on a vacuum check valve assembly. The vacuum hose installation should start with installing the clip before proceeding to install the brake master cylinder push rod clevis along with the brake pedal return spring and brake master cylinder sub-assembly. Both C59 and E351 models require a manual transaxle operator to connect the clutch pipe followed by brake fluid filling before bleeding the same clutch line in both vehicles. Next proceed to bleed the brake master cylinder as well as the brake line and brake actuator (with VSC) while inspecting for any brake fluid leaks and checking fluid levels and performing brake pedal height inspection followed by free play and reserve distance adjustment. Proceed to the final installation step by tightening the front wheel LH to 103 Nm (1050 kgf-cm, 76 ft-lbf) torque before finishing all parts such as the air cleaner case and its sub-assembly and the air cleaner cap sub-assembly with the cylinder head cover and suspension tower damper assembly and outer cowl top panel and windshield wiper motor and link assembly and cowl top ventilator louvers and hood to cowl top seal and front wiper arm and blade assemblies.
