If you change the fluid on a car that old that still has it's 
original fluid, you'll be horrified at what it looks like when it 
comes out. It will be brown, filled with mud. Cars with a cast iron 
reservoir on top of the MC will be especially bad. That reservoir 
will appear to have a layer of mud sediment on the bottom.

And it's not mud. It's iron oxide from all the metal surfaces inside 
the brake system. And it doesn't take 20 years; it can happen in 5 to 
8 years.
