• Q: How to service and repair the Vacuum Brake Booster on 2000 Toyota Echo?

  A: The Vacuum Brake Booster service process starts with master cylinder removal along with air cleaner assembly and ABS actuator removal followed by vacuum hose unattachment from the brake booster. Begin by taking out the return spring and clip and clevis pin and afterward remove the brake booster through uninstalling the 4 nuts and clevis before gradually pulling the brake booster with its gasket. Install the brake booster assembly with new gasket after placing it in position before torquing the booster installation nuts to 13 Nm (130 kgf-cm, 9 ft. lbs.) for the following step of installing and torquing the clevis lock nut to 26 Nm (260 kgf-cm, 19 ft. lbs.). After inserting the clevis pin into the clevis and brake pedal it must be secured with the clip before installing the return spring. A brake master cylinder replacement requires measuring the clearance between a push rod and an accessory tool that should sit directly against the brake booster until the measurement indicates 0 mm (0 inch). Follow these instructions to adjust the push rod length only when the clearance deviates from specifications but keep in mind to perform the adjustment when the booster maintains no vacuum by performing brake pedal depression multiple times while the engine is off. The brake system requires filling with brake fluid after the vacuum hose connection and subsequent master cylinder and ABS actuator installation together with the air cleaner assembly. Complete the inspection by testing for leaks and checking and adjusting brake pedal operation followed by performing an operational test.
