I have two bottles of Motul RBF600 brake fluid that I would like to use, but I'm pending new pads and rotors before using them. These bottles are still sealed in their original bottles. The only questionable factor is that I've had these two bottles for at least 2 years.

I know that opened bottles of brake fluid are useless, but does the same go for closed/sealed bottles that have been sitting for an extended period of time?

Thanks!

 

They will be perfectly fine if they are sealed.

 

Air tight = good to go. Squeeze the bottle with everything still sealed. s long as no air leaks out (even the slightest bit) then no moisture could have gotten in.
