Having a brake booster vacuum issue.
Think my booster is leaking and removed the check valve
at the booster. Hooked up my mighty vac pump tool and
will not hold a vacuum. Made sure was sealed tite.
Wondering if the volume of the booster diaphram to
great to pull down vacuum. Trying to pin point before
throwing parts at it.
Haven't ever seen or had an issue with this before. Check
valve tests out good. Car 20 years old so I guess the little things catching up.
Tried same thing on my aux vacuum ball and it won't pull
vacuum either.

Any brake booster guru's out there and comments
