On-Vehicle Inspection and ServiceEFS000CC
FUNCTION INSPECTION
With the engine stopped, discharge stored vacuum by depressing
brake pedal several times at 5 second intervals. With the brake
pedal fully depressed, start the engine.between Confirm that clear-
ance between brake pedal and the floor panel decreases when
engine vacuum stabilizes.
AIRTIGHTNESS INSPECTION
lRun the engine at idle for approximately 1 minute. Stop it after
applying vacuum to the booster. Depress the brake pedal sev-
eral times with normal force to discharge the stored vacuum.
Confirm that clearance between brake pedal and the floor panel
gradually increases as the brake pedal is depressed.
lRun the engine. Depress and hold the brake pedal then stop the
engine. Keep the brake pedal depressed for 30 seconds or more
and make sure the pedal stroke does not change.
Removal and InstallationEFS000CD
REMOVAL
CAUTION:
lBe careful not to deform or bend brake piping while removing and installing the brake booster.
lReplace clevis pin if it is damaged.
lBe 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.
lBe sure to install the check valve in the correct orientation.
1. Remove vacuum piping from the brake booster.
2. Remove master cylinder.
3. Remove snap pin and clevis pin on passenger compartment clevis. Remove input rod from the brake
pedal.
4. Remove brake booster and brake pedal assembly mounting nuts.
5. Remove booster assembly from the engine compartment.
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. Place an output rod gauge in the master cylinder. Rotate the
screw until the gauge contacts the primary piston.
3. Turn output rod gauge upside down to secure A. Adjust it with B
until clearance between output rod and screw is 0 mm.
INSTALLATION
1. Loosen lock nut to adjust input rod length so that length B (in the
figure) satisfies the specified value.
2. After adjusting B, temporarily tighten lock nut to install booster
assembly to vehicle.
3. Connect brake pedal to input rod clevis.
4. Connect brake pedal assembly mounting nuts and tighten to the
specified torque.
5. Connect master cylinder to the booster assembly.
6. Adjust brake pedal height and play.
7. Tighten input rod lock nut to the specified torque.
8. Bleed air. Refer toBR-10, "
Bleeding Brake System". Reference value at vacuum of -66.7 kPa (-500 mmHg, -
