Brake Fluid

[r31slpr]

I had a few bottles of brake fluid sitting in the boot of my car for a couple of days and when i pulled them out i noticed condensation on the bottles.

I know that brake fluid is hygroscopic but will the plastic bottle be porous enough to let moisture through into the fluid?

So should i use them or chuck them out? Only one of the bottles has been opened so far, so the others are sealed.

Cheers

If they were porous you would have brake fluid everywhere.

Having said that, ditch the open one, keep the others. Mostly because it is poor practice to have open bottles of brake fluid laying about.
