If you rebuild your own TreadleVac which I don't recommend unless you're very familiar with that unit, you can use any brake fluid you want, but note that two of the premier rebuilders of these units void their warranty if you use DOT 5. Or at least that was their position a year or two ago. I've used DOT 5 in earlier Packards with excellent results, but in the many cars, Packards, Mercurys, Lincolns and some GM cars, that I've serviced with TreadleVacs I've always used DOT 3 or DOT 4 and have never had a problem with any of them. That said, I do purge the old fluid and refill every 2 or 3 years.
