Operating Check

OPERATIONAL TEST OF BRAKE BOOSTER



NOTE: If there is leakage or lack of vacuum, repair before testing. If available, use a brake booster tester to check the booster operating condition.

- Depress brake pedal several times with engine stopped, and ensure that pedal reserve distance does not change.
- Depress brake pedal and start engine. If pedal drops slightly, operation is normal.
