  • Who told you that? I don't think the color really matters. Mine must be REALLY wrong, it is clear. Are your brakes working? If so, why worry?
  • Brkae fluid is hygroscopic and will absorb water over time. This decreases it's boiling point, which will allow the fluid to boil under normal braking circumstances. Fluids don't compress, which is why hydraulic braking systems are so effective, however if the brake fluid begins to boil, it will turn into a gas, which is compressible, and can cause you to lose all, or most, of your braking ability. That said, I don't believe color is a reliable indicator of water absorption. Several methods exist to measure the amount of moisture in the fluid, however it's generally recommended to change brake fluid every two years. (Which, I bet, has been done to less than 1% of cars out there.) Color might indicate that the wrong type of brake fluid has been added to the system. There are several classes of brake fluid. DOT 3 is most likely what your vehicle calls for, unless it's a specialty import car. Some of the types of brake fluid DO NOT mix, because the seals and rubbers used within the systems are different. If you put DOT 5 in a DOT 3 system, it will swell the seals and hoses, eventually causing a leak. Leaks, of course, being detrimental to the workings of a hydraulic system. If your car is stopping properly, and you are certain that only the correct fluid has been added to your system, I'd say that you have little to worry about, especially if it's a newer car. Still, it would be a good idea to get it changed just for safety's sake.
  • brake fluids are almost always clear in color,except some synthetics are blue in color.brake fluid does become discolored after time picking rust deposits and normal wear and tear.usually this looks dirty,kind of brownish.red....usually tranny fluid color.
