Should I "fix" if it is not broken??

Ok the I have no leaks within the brake system on my '86 Tudor.

That being said, the fluid has been in there for at least five years, save for last year when I used a baster to suck out the fluid from the master and refill.

But I realize most of the fluid remains in those lines and in the wheel cylinders.

So do I call my bud and have the brake fluid changed?........

Yes. If it's been in there more than two years it's a good idea to change all of it. Brake fluid is hydroscopic - it will attract and contain moisture.

If you think the bleeders will actually open up go for it, otherwise I'd leave it alone.

If the bleeders open, flush it. If they don't want to open, don't force them and get what you can get. Or just replace the parts that the bleeders wont open on since they are essentially shot anyway.

A bit of "Free All" or some other rust penetrating oil on the bleeders. Let sit overnight. Fresh shot of oil on them all and wait a couple of minutes before you start to loosen them in the morning. This often makes the difference along with a six sided tool.

I've been reading good things about the famed 50/50 mix of acetone and tranny fluid. No idea if special considerations come into play for brake bleeders though.
