If the CPP kit with manual brakes had any easier pedal effort the pedal would be too sensitive and it would be easy to brake too much. I'm guessing they use a really aggressive pad compound to get it to stop with minimal pedal pressure but it works great with a 1" manual MC.

Changing brake pad compound can make a huge difference in pedal effort; my car with boosted brakes was really hard to stop and the brakes felt inadequate when I first bought it. I let my dad drive it and he agreed that something was wrong with the brakes. Pedal effort was excessive in normal driving, and it took a ton of pedal pressure to get it to stop really quickly. I swapped to Centric PQ Pro semi-metallic pads, bedded the pads in, and the pedal effort is now normal. I could see a truck with ceramic pads needing a booster, they have a very low coefficient of friction and would need more line/pedal pressure to stop the truck.
