• Q: How to service and repair the Vacuum Brake Booster on 2005 Toyota Echo?

  A: Initiating Vacuum Brake Booster service and repair requires taking off the master cylinder first and also the air cleaner assembly together with the ABS actuator before unclipping the vacuum hose from the brake booster. First remove the brake booster return spring and clip along with the clevis pin before extracting both the brake booster with gasket through the removal of four installation nuts and clevis. Install the new gasket and booster onto the vehicle before installing and torquing the booster installation nuts to 13 Nm (130 kgf-cm, 9 ft. lbs.) and then torquing the clevis and lock nut to 26 Nm (260 kgf-cm, 19 ft. lbs.). Fasten the clevis pin inside the clevis to brake pedal while securing it with the clip before reattaching the return spring. To replace only the brake master cylinder adjust the brake booster push rod by placing chalk on an accessory tool tip then measuring the tool to push rod clearance until it reaches 0 mm (0 inch). Use Special Service Tool: 09737-00020 to fix the push rod and adjust the protruding adjusting bolt length while ensuring this operation takes place with no vacuum in the booster along with several pump actions on the brake pedal when the engine is off. The next steps require installation of the brake booster vacuum hose followed by reinstallation of the ABS actuator and air cleaner assembly and master cylinder. Additionally, users should fill the brake reservoir with brake fluid and perform a brake system bleeding process. Perform an operational check along with verifying and adjusting brake pedal then search for any remaining leaks.
