Brake fluid trick for leaky steering box?

[71CHEVYSHORTBED402]

I had my steering box rebuilt by reputable. It sat around a few years, something went wrong, perhaps the pitman seal just dried up. Man it bugs me, but really, at this point, I just don't like the idea of messing with it. I think you have to pull the skirt off, risk paint damage etc. So at this point, at least the fluid is always fresh.

A well-seasoned reputable guy tuned up my carb. today for its "500 mile check-up" following a restoration. Man, he dialed it in to, best its ever run. Anyway, he says put a splash of brake fluid in the PS reservoir, not too much, perhaps an ounce.

He didn't believe it himself until his brother did it "for steering box only". Fixed the problem and never to be heard from again, apparently it swells up the seal for you. I wouldn't expect any damage to the finish, though, I don't know, I suppose a guy doesn't have to use DOT3, I should ask him, but I'm mostly sure he meant DOT3. On that note, I hear silicone swells seals too. Hmm.

What do you think?

Speak of, anyone know off hand how much you're supposed to fill a remote PS reservoir? I've always figured about 1/2-3/4" from its top. Doesn't seem a big deal, so long as it's attended to and doesn't spill. Happen to know what the fluid capacity is, box, hoses, reservoir and pump?
