help hard break pedal weak breaks after swap

valve was used but looked very nice

only one line on booster to hook up and its hooked to rear intake runner driver side where every one said to run it
adjusted the rod end to meet the pedal when installed so should be no preload there
car rolls perfect when pushing it n neutral so i wouldint say theres any drag

all new rubber lines two

i wonder if i should install my old distribution valve just for the heck of it and see what happens but that was from a drum break car
