This will be my 1st time flushing the fluid and wanted to know how much fluid is needed for a complete flush?
After reading a several brake fluid threads, I know understand the difference between dry and wet boiling points. However I can't seem to find any info that explains how long it takes a hygroscopic fluid to absorb moisture - Is there a general rule of thumb guideline for the rate of change of moisture absorption?
Also, since I'm not tracking my M900, shouldn't I give more weight to wet boiling point specs?
A normal 500ml bottle should be plenty. Even if you have to do multiple bleeds due to air in the system you should still have some left over.
it depends on a LOT, such as use, humidity, seal of the system and so on.
best rule of thumb is the color of the fluid. once it starts getting cloudy, then it has water. however, it still performs pretty well even after it's started to absorb
the key is to use a good fluid that resists moisture. i have used Castrol LMA for years and love it.
