hi John,
you say 'brake fluid is up'...
but you didn't start driving a van that's been sitting 10 years and not
immediately change the brake fluid did you ???
I even change the brake fluid on my parts vans when I get them..
that's how old and watery bf gets sitting for years.
And how very bad it is for the brake components to have watery brake fluid
in them..
it just ruins them.
so if you have not ..
do change the brake fluid.
if you use a manual method ...........don't stroke the brake pedal very
far..
no lower than half way down.
it's not sounding good ..
but in all cases..
changing brake fluid is a *diagnostic* procedure ..
not just a service procedure.
How it acts when you do that ........tells you a lot.
I prefer a manual bleed method as you can easily feel and tell what the MC
is doing ..
like if it's pumping air or not.
re the booster..
mainly you make sure the whole rest of the brakes are good..
and that vacuum is getting to the booster..
and then after that you can start thinking about if it's faulty or not.
maybe your brake fluid is so watery you could make tea with it.
but I hope not !~
