FWIW,
On my '74 the aluminum banjo fitting which connects the brake vacuum hose
to the brake booster canister contains a check valve.
I have verified that you can pull air thru this fitting in the direction
of the vacuum hose, but you cannot blow air thru the fitting from the vacuum
hose end.
The purpose of the check valve to retain a vacuum in the booster canister
if the engine is turned off and to protect the canister diaphragm in the
event of a backfire.
Have fun,
