1979 f600
my front brakes are locked up I’ve replaced master cylinder
all wheel cylinders
hydro vac component
all vacuum lines
and the hydro check valve on the fire wall
bled brakes many times
I’m thinking since those things that go into the brake shed itself are gone that might be the issue ?
Before
Before
And getting closer
And getting closer
I lost the little metal nub things that go in this hole What are they what do they do

You need a shop manual or at least some clear illustrations if you are going to work on this truck, especially brakes:
