The van has sat since any work was done - like September last year.
The brake fluid was changed. It was nasty. It may need to be changed
again - but I wouldn't think so. But, whatever it takes......
Perhaps even the rear brake cylinders need changing out - though there
is o leakage. Just dunno. I really hate to think about having to change
out the booster. Changing the maser cylinder is not to much of a biggie.
