• Q: How to service and repair the vacuum brake booster on 2001 Toyota Corolla?

  A: You need to start vacuum brake booster repairs by picking off the master cylinder and removing the brake booster vacuum hose then pulling off the pedal return spring. First remove the clip and wave washer and clevis pin while the brake booster installation involves removing four nuts from their position to detach the clevis before pulling out both the booster and gasket. Installation of the brake booster starts with the new gasket then it receives the operating rod clevis before torquing booster installation nuts to 13 Nm (130 kgf-cm, 9 ft. lbs.). To install the clevis pin insert it through the wave washer next to the brake pedal and the clevis before attaching the clip to the clevis pin alongside the pedal return spring. Use the gasket to position the master cylinder while setting Special Service Tool: 09737-00010 on the gasket to adjust the booster push rod pin length until it contacts the piston. Place the upside-down Special Service Tool: 09737-00010 above the booster and measure the booster push rod and pin head gap which should register 0 mm (0 inch). Modify the booster push rod length to make it gently brush against the pin head while pressing the brake pedal enough during adjustment. Install the master cylinder before connecting the vacuum hose to the brake booster and adding brake fluid into the reservoir and performing brake system part bleeding. The procedure requires leak checks followed by brake pedal adjustment accompanied by clevis lock nut tightening to 26Nm (260 kgf-cm, 19 ft. lbs.). An operational check should be conducted last.
