Changing the brake fluid on my '90 100

[Brooks Ellis <brooks@fortnet.org>]

   I was reading somewhere that brake fluid should be clear. Mine is as 
brown as motor oil. It hasn't been changed since I got it ~1-1.5 years 
ago, and it doesn't look like it was changed anytime recently before 
then. I was going to change my brake fluid, but then I realized, I had no 
idea on how to do it! 
   Do people on this list commonly do such a change? Would someone be 
gracious enough to give me some 'idiots guide to brake fluid changing' 
text? 

Thanks in advance...
