Brakes feel like I have no brake booster

[Project Nico]

I have a 1979 C10 Cheyenne. It has disc brakes in the front and drums out back. When I bought I did not brake with confidence. I have since replaced the calipers, front brake hoses, resurfaced the rotors and new pads. The drums were turned and new shoes and hardware. The system was bled on all four corners...starting with the farthest. The truck brakes better, but I still don't brake with confidence. I have to press the pedal with a lot of pressure. Thanks for the help in advance. Oh I forgot to mention that I broke in the brakes already.
