It has never occured to me to stick anything soft and pointy into an
automotive brake line !

there are two very simple solutions..
for a metal brake line, to cap it off, slide the nut back, put a rubber
bleed valve cap on the flared end.

for a hose ..
scrounge an old metal brake line off a dead vanagonsomewhere..
cut it short, like 2 inches..
smash or flatten the cut end ..
and there's your hose blocker offer.
