| * Brake fluid (3,4 & 5.1) is hygroscopic (able to draw in moisture like a sponge). \\ It is no wonder, then, that the brake fluid in the master cylinder is often dark, almost black in appearance. \\ But does that mean it has to be changed? Not always. \\ Glycol based fluid absorbs moisture and disperses it throughout the system. \\ Silicone based (5) fluid does not allow moisture to enter the system. So this test may not work for DOT 5 fluid. ((steelworker of the XLFORUM http://xlforum.net/forums/showthread.php?t=1227590)) \\ (since it's the moisture inside the fluid that makes the reaction) \\ And while there are test strips to test the moisture content, \\ Here is a method that works just as well. \\ Use your DMM (Digital Multimeter) to test the fluid. | * Brake fluid (3,4 & 5.1) is hygroscopic (able to draw in moisture like a sponge). \\ It is no wonder, then, that the brake fluid in the master cylinder is often dark, almost black in appearance. \\ But does that mean it has to be changed?
