Re: brake boosters: hydro vs. dual dia. vacuum
Your booster can be rebuilt. Had mine done a few years back for $85 at Power Brake Booster Exchange in Portland, OR, (I'm on the road, so not positive of the exact name). If you were happy with your brakes before the problem, send it out to be rebuilt, they advertise in Hemmings. If you need more boost, I'd suggest a dual diaphram booster. When I converted to 4 wheel disk, I had to replace my stock booster with a dual diaphram booster from a Scout II along with a proportioning valve. I've heard that Ford Granadas and their Mercury clone have dual diaphram boosters that can be used. Might check the wrecking yards. One thing about the hydro-boost to consider is if your engine dies, so does your boost. The vacuum boost at least has a pump or two left as reserve when the engine dies.
