• Q: How to service and repair the Vacuum Brake Booster on 2002 Toyota Celica?

  A: The service and repair process for Vacuum Brake Booster begins with front LH wheel removal at specified torque of 103 Nm. You should remove the master cylinder while disconnecting the vacuum hose from the brake booster. Service and repair operations must start by removing the ABS actuator assembly when the vehicle system includes this component. Begin by using Special Service Tool: 09751-36011 together with a spanner to detach the front LH brake line from the flexible hose before you pull out the brake line with its grommet from the body. Begin by removing the brake booster after taking off the lower No. 1 panel and finish panel and proceeding to delete the return spring, clip and clevis pin and finally the clevis and 4 nuts before pulling out the brake booster and gasket. Begin the installation process by applying new hardware consisting of a gasket together with a brake booster before tightening the 4 nuts to 13 Nm (130 kgf-cm, 9 ft. lbs.). After this, attach the clevis and fasten its lock nut to 25 Nm (260 kgf-cm, 19 ft. lbs.). Place the clevis pin in the clevis then the brake pedal before securing it with the clip followed by adding the pedal return spring. The front LH brake line preparation involves guiding the grommet-inserted tubing into the body and connecting it to the flexible hose through the use of Special Service Tool: 09751-36011 and a spanner while torquing it to 15 Nm (155 kgf-cm, 11 ft. lbs.). The installation of the ABS actuator assembly must take place first when ABS is present. The process of master cylinder brake replacement requires the brake booster push rod clearance adjustment by using an accessory tool to mark the brake booster and measuring any specified distance which should remain at 0 mm (0 inch). The brake pedal depression and adjustment of the push rod length should be performed only when the brake booster maintains no vacuum. The next steps involve connecting the vacuum hose to the brake booster while installing the master cylinder followed by brake fluid addition into the reservoir then performing brake system bleeding. Inspect fluid leaks before testing the brake pedal operation and adjusting itself until ready for the finish panel along with the lower No.1 panel installation. Finally, perform an operational check.
