        Start the engine and stop it after 1 or 2 minutes. Slowly depress the brake pedal several times.

        Tech Tips

        If the pedal can be depressed to the floor the first time, but on the 2nd and 3rd times cannot be depressed as far, the booster is airtight.

      2. Depress the brake pedal while the engine is running and stop the engine with the brake pedal depressed.

        Tech Tips

        If there is no change in the pedal reserve distance while holding the pedal for 30 seconds, the booster is airtight.
