REMOVAL
CAUTION:
Be careful not to deform or bend brake piping while removing and installing the brake booster.
Replace clevis pin if it is damaged.
Be careful not to damage brake booster stud bolt threads. If brake booster is tilted or inclined dur-
ing installation, the dash panel may damage the threads.
Attach the check valve in the correct orientation.
1. Remove vacuum hose from the brake booster. Refer to BR-25, "
VACUUM LINES" .
2. Remove the brake master cylinder. Refer to BR-24, "
Removal and Installation" .
3. Remove the brake piping between brake master cylinder and ABS actuator and electric unit (control unit).
Refer to BR-12, "
Hydraulic Circuit" .
CAUTION:
For M/T vehicles with remove the brake piping after removing the clutch reservoir tank bolt.
4. Remove the brake pedal attachment snap pin and clevis pin from inside the vehicle.
5. Remove the nuts on the brake booster and brake pedal assembly.
6. Remove brake booster assembly from the engine compartment side.
INSPECTION AFTER REMOVAL
Output Rod Length Inspection
1. Using a handy vacuum pump, apply a vacuum of −66.7 kPa (−
500 mmHg,−19.69 inHg) to the brake booster.
2. Check output rod length.
INSTALLATION
1. Loosen the lock nut to adjust the input rod length so that the
length “B” (in the figure on the right) satisfies the specified value.
2. After adjusting “B”, temporarily tighten the lock nut to install the
booster assembly to the vehicle. At this time, make sure to
install a gasket between the booster assembly and the vehicle.
3. Connect the brake pedal with the clevis of the input rod.
4. Install the pedal bracket mounting nuts and tighten them to the
specified torque.
5. Install the brake piping between brake master cylinder and ABS
actuator and electric unit (control unit). Refer to BR-12, "
Hydraulic Circuit" .
6. Install the master cylinder to the booster assembly. Refer to BR-24, "
Removal and Installation" .
7. Adjust the height and play of the brake pedal. Refer to BR-7, "
ADJUSTMENT" .
8. Tighten the lock nut of the input rod to the specified torque. Refer to BR-23, "
Components" .
9. Refill new brake fluid and bleed air. Refer to BR-11, "
Bleeding Brake System" . Standard dimension when vacuum −66.7 kPa
