System" .
Inspection After InstallationAFS001N1
CAUTION:
If a leak is detected at the connections, retighten it or, if necessary, replace the damaged part.
1. Check brake lines (tubes and hoses), and connections for fluid leaks, damage, twist, deformation, contact with other parts, and loose connections. Replace any damage parts.
2. While depressing brake pedal under a force of 785 N (80 kg, 177 lb) with engine running for approximately 5 seconds, check for fluid leakage from each part. : 23.5 N·m (2.4 kg-m, 17 ft-lb)

On-Vehicle ServiceAFS001N6
OPERATING CHECK
With engine stopped, change the vacuum to the atmospheric pres-
sure by depressing brake pedal several times. Then with brake
pedal fully depressed, start engine and when the vacuum pressure
reaches the standard, make sure the clearance between brake pedal
and floor panel decreases.
CAUTION:
Depressing pedal interval is approximately 5 seconds.
AIRTIGHT CHECK
Run engine at idle for approximately 1 minute, and stop it after
applying vacuum to booster. Depress brake pedal normally to
change the vacuum to the atmospheric pressure. Make sure dis-
tance between brake pedal and floor panel gradually increases.
Depress brake pedal while engine is running, and stop
engine with pedal depressed. The pedal stroke should not
change after holding pedal down for 30 seconds.
CAUTION:
Depressing pedal interval is approximately 5 seconds.

REMOVAL
CAUTION:
Be careful not to deform or bend brake piping while removing and installing 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, dash panel may damage the threads.
Attach the check valve in the correct direction.
1. Remove brake piping from brake master cylinder.
2. Remove brake master cylinder. Refer to BR-13, "
Removal and Installation" .
3. Remove vacuum hose from brake booster. Refer to BR-18, "
VACUUM LINES" .
4. Disconnect harness connector from brake booster assembly. (ICC model)
5. Remove brake pedal attachment snap pin and clevis pin from inside the vehicle.
6. Remove nuts on brake booster and brake pedal assembly.
7. Remove brake booster assembly from dash panel.
