BRAKE BOOSTER ASSY (From July, 2003)
ON-VEHICLE INSPECTION
1. INSPECT BRAKE BOOSTER
(a) Air tightness check.
(1) Start the engine and stop it after 1 or 2 minutes. De-
press the brake pedal several times slowly.
HINT:
If the pedal goes down farthest the 1st time, but gradually rises
after the 2nd or 3rd time, the booster is air tight.
(2) Depress the brake pedal while the engine is run-
ning, and stop the engine with the pedal depressed.
HINT:
If there is no change in the pedal reserve distance after holding
the pedal for 30 seconds, the booster is air tight.
(b) Operating check.
(1) Depress the brake pedal several times with the igni-
tion switch OFF and check that there is no change
in the pedal reserve distance.
(2) Depress the brake pedal and start the engine.
HINT:
If the pedal goes down slightly, operation is normal.
2. INSPECT VACUUM CHECK VALVE
(a) Check vacuum check valve.
(1) Slide the clip and disconnect the vacuum hose.
(2) Remove the vacuum check valve.
(3) Check that there is ventilation from the booster to
engine, and no ventilation from the engine to the
