The issue is far to random for me to wrap my mind around it. in the past when a vaccum hose has a break it in or it is collapsed it tends to stay that way and have a constant. However due to the brake hardening up i still go back to the vaccum as its all vaccum based.
This may seem like an asinine statement: But have you checked the vacuum hose that goes behind the power box?
The brake booster that goes in the master cylinder? It's made of hard plastic I believe. But there's a different type substance it conjoins into.
