• Q: How to service and repair the Vacuum Brake Booster on 2001 Toyota Celica?

  A: The service and repair process for the Vacuum Brake Booster starts with front LH wheel removal at a torque of 103 Nm (1,050 kgf-cm, 76 ft. lbs.). The first step consists of removing the master cylinder and breaking off the vacuum hose that connects to the brake booster. Service technicians should use Special Service Tool: 09751-36011 along with a spanner to disconnect the front LH brake line from its flexible hose before removing both the brake line with integrated grommet from the body. To remove the brake booster first remove the lower No. 1 panel and finish panel before taking out the return spring, clip and clevis pin, then remove the clevis and 4 nuts, until the brake booster and gasket can be pulled out. First install a new gasket as well as brake booster before tightening its 4 nuts to 13 Nm (130 kgf-cm and 9 ft. lbs.) and then install the clevis followed by tightening the lock nut to 25 Nm (260 kgf-cm and 19 ft. lbs.). The next process requires you to put the clevis pin into both clevis and brake pedal before installing the clip to secure it and adding the pedal return spring. Install the front LH brake line by feeding in the grommet and attaching it to the front LH brake flexible hose with the use of Special Service Tool: 09751-36011 and a spanner while torquing to 15 Nm (155 kgf-cm, 11 ft. lbs.). Installation of the ABS actuator assembly should proceed only after system equipping. To properly adjust the brake booster push rod during master cylinder replacement use an accessory tool with chalk marking applied to its tip which you place on the brake booster to measure clearance until reaching the target 0 mm (0 inch). Use an accessory tool to measure push rod length adjustments on the brake booster but ensure the brake system maintains no vacuum while depressing the pedal multiple times after shutting off the engine. The brake booster receives the vacuum hose followed by master cylinder installation while brake fluid fills the reservoir before finishing with brake system bleeding. After verifying fluid leakage you must check and set the brake pedal then reinstall the finish panel together with the lower No. 1 panel. Finally, perform an operational check.
