Upgrade to power brakes from manual

[mschwader]

Anyone upgrade their manual brakes to power? I have only the main brake cylinder in the engine bay for brakes. Looks like it only stops the front wheels and not the rear. I know having manual brakes makes for really hard breaking and stopping but I feel kike it shouldn't be so hard to stop. I can put tremendous pressure on the brake pedal and it seems like it barely gives. Are there any maintenance suggestions out there. I feel like the pedal should depress a lot more than it is. I just got the truck running and now I want to be able to drive it around a little while I am working on the restore.
