I have a 2017 Honda. The brake pedal falls about an inch when the engine starts. Is this normal, do I need service?

    Hi yes that is correct as the vacuum servo takes effect.

    Normal, as vacuum is building.

    That's the power assist for the brakes coming on.

    That is normal. That is also the procedure when checking if the brake booster works.

    An inch might be excessive.

    But your power brakes provide power assist only when the engine is running, and producing vacuum at the booster. A bit of pedal drop is normal, especially if you're holding pressure with your foot.

    Your brake booster works. It runs off engine vacuum.

    NO, it isn't normal, and indicates something bad is going to happen to you if you don't get it fixed.
