I've had the experience of taking a car to someplace to work on it,  at which 
point the brakes worked fine,  and then when I went to move it there weren't 
any brakes at all -- the master cylinder simply shot brake fluid out...
What I'd like to know,  though,  is how that point "rusts" in the first 
place, since there shouldn't be any air in there.
By rights,  though,  anything that's a couple of decades old or more should 
be suspect when it comes to *any* rubber parts,  seals,  bushings,  whatever. 
I've had problems of this sort more than once,  since I tend to drive lots of 
older stuff...
