Dark Brake Fluid
Hey guys, I got an issue, I was taking a look to see if I have enough brake fluid and I noticed that my brake fluid was very dark (greyish) and I know that the brake fluid is a clear yellowish orange, I'm gonna make an appointment for service but was wondering if anyone knew whats going on? The coupe seems to give me a lot of black liquids lately
the engine oil was black, the brake fluids black

You need to change it right away! Brake fluid absorbs moisture, which is by design. As it does, it gets darker in color. There are two problems with brake fluid that has a lot of moisture in it - the boiling point of the fluid is lowered a lot, and the internal components of the hydraulic unit can be damaged from the moisture.
When the owner's manual says that it should be changed every two years, they aren't joking!
