Vacuum Brake Booster: Testing and Inspection

OPERATING CHECK

^

With the engine stopped, change the vacuum to the atmospheric pressure by depressing the brake pedal several times. Then with brake pedal fully
depressed, start the engine. When the vacuum pressure reaches the standard, check that the clearance between the brake pedal and floor panel
decreases.

CAUTION:   Depressing pedal interval is approximately 5 seconds.

AIRTIGHT CHECK

^

Run the engine at idle for approximately 1 minute, and stop it after applying vacuum to the booster. Depress the brake pedal normally to change
the vacuum to the atmospheric pressure. Check that distance between the brake pedal and floor panel gradually increases.

CAUTION:   Depressing pedal interval is approximately 5 seconds.
