Air in the brake system causes a spongy pedal because air compresses where brake fluid doesn't. If the pedal is hard and takes a lot of effort, you might need more assist. Or the pedal ratio can be changed or use a smaller master cylinder bore. That will decrease effort but increase pedal travel. It's a balancing act.
