I'm reading conflicting information about brake fluid absorbing water.
In real world situations is brake fluid that's been open for 4 months (stored in the garage with lid tightly fitted) ok to use?

I ask because if brake fluid absorbs water at such an alarming rate, surely it's not that much better in the car reservoir....

BTW the fluid I've just changed has been in my bike for 10+ years so the 4 month old fluid must be an improvement, right?
