Unhappy Weak brakes after removing intake box

I need help solving a lack of brake power. I removed the intake off the motor when I removed the head. I wanted to repair a broken valve spring, bent push rod and check why it broke. After replacing the head gasket and the head, I reinstalled the air box and other parts. I now have no power brakes or a/c. Please give me some assistance in finding where to look. The cooling fan is running as if the a/c is on, but the compressor is not turning.

Did you re-attach the vacum hose coming from the intake Manifold to the brake booster?

I replaced the air line coming from the back of the intake to the brake booster, but there is a second hose bib on the front of the brake booster. Should it be closed?

The smaller of the two vacum hoses goes to the purge valve. The small nib on the booster check valve is usually capped

The A/C part may be a missing connection to the compressor. There is a small vacuum connection to the intake near the throttle body. That one popped off when I did my valve spring project.

If you like gauges - add a simple 'old school 60's style' vacuum gauge to your truck - it can help with simple diagnostics and give some indication of where your fuel mileage might be in real time as you drive...but I really just like seeing the needle jump-around .

Everyone needs a vacuum gauge! I really like mine when it swings to the right of "0".....
