About 6 years ago I purchased a 56 century riviera. The previous owner removed the mechanical fuel/wiper vacuum pump in favor of an electric fuel pump. When he did so he moved the wiper vacuum line to a fitting by the brake master cylinder. The brake pedal feels like it’s much to firm and requires what I consider more effort than it should to stop the car. Did he inadvertently reduce the power brake effectiveness? If I reinstall a factory type fuel/wiper vacuum pump and keep the electric as a primer, should the brake pedal return to what I consider easier to press?
