Humidity/Participation vs Brake Fluid
 

One of the reasons and the purpose of flushing the brake fluid ~ 2 years is because it absorbs moisture. Does it make sense to flush the brake fluid in a humid climate or rainy day because it may absorb the moisture in the air as you replace it?

I have one of these and the Indie Seth in Jax FL uses one of these when doing a inspection. It will tell you if your brake fluid has a certain level of moister. I just checked the Brake fluid in my Truck and it has been over two years and needed to be changed. Moister was bad! Better pedal now since changing fluid.

Participation or precipitation?

You don't need to worry about the time (~1 hour) that the fluid is exposed to the air (whether humid/rainy or dry) during the flush and bleeding procedure.

You do need to worry if you left the reservoir cap off for a week.

Perhaps I was being too critical.

Lol! Precipitation is the correct term.
