Hi Carl, I think perhaps you had some bad luck or strange brake fluid.  I
have not seen an automotive brake master cylinder or ABS unit or wheel
cylinder or ( place your favorite brake component here ) that was NOT made
out of aluminum in at least 15 years.  I am positive DOT-4, DOT-5 brake
fluid does not corrode aluminum. -- Ian

I used to use a brake bleeder on my car which was made of aluminum.  I
also have a Mighty Vac hand pump that I also used to bleed brakes.  Both
of them corroded to the point that I had to throw them away.  Lesson
learned......don't let aluminum get in contact with standard automotive
brake fluid.
