This is a very interesting article I came across on brake fluid..

Cool trick for storing Unused brake fluid

 

One trick you can use (sometimes) is to squeeze the bottle once you're done using it until the fluid comes just up to the lip, then cap it off. If the cap seals well enough to keep air from entering, it should keep for a time. Even if air does goes in, you can see from the shape of the bottle.

 

I experimented with my "expired" RBF600. Surprising, the bottle is air-tight and stay in shape.

Ups......Good piece of info....

I do read before some ppl charge the bottle with some Nitrogen before capping off the brake fluid to preserve it.

I believe the hygroscopic properties of some brake fluid like RBF600 is more obvious in high humid country like Singapore.

 

The higher the boiling point of the fluid (the better they are), the higher is the rate of moisture absorption from surrounding.

 

I checked Singapore humidity is around 90% in the morning and drop to 60% in afternoon.

 

So.....the best time to flush your brake is ....in the afternoon..

 

Or if possible, a humidity controlled environment such as air-con places.

Hee...someone should open an aircon workshop.

[FieryGiX]

Hm...I wonder why no one has.

 

If I open my own garage, I sure install air-con for my mechs and customers.

the fumes from exhaust inside the workshop...

mezzo used to have 1, but not anymore.

a knowledgeable K5 owner once adviced me to always use a fresh bottle. lucky for me, mj and me have our own r6. so, one bottle every 2 - 3 mths does the job.

My left over RBF600. Took some skill to squeeze out all the air and cap it tight.

 

Now, when I shakes it, no splashing sound...NO AIR!!!

so brake fluid, once exposed to the air, is useless? Is there a 'shelf life'?

[FieryGiX]

I think it's more of a constant exposure to air.

 

All I know is brake fluid absorb moisture from surrounding air. How fast or how much it absorb? That's a question for the manufacturer.

 

What we can only do is to minimise exposure to air once factory seal broken.

 

As for shelf life, I believe as long as the factory seal is intact, the content should be okay for as long as possible.
