Question on old brake fluid...
A couple years ago, I bled my brake system with Super Blue, and had a bunch left over. It's been sitting in my house since. Was curious if it would be okay to use it for another bleed. I know certain things have a shelf life, but I wasn't sure if it's just the pressurizing inside the system that breaks down the fluid, or if it actually ages on the shelf.
Any help would be greatly appreciated!!

Conventional glycol-based brake fluid is hygroscopic, which means that it absorbs water. It's probably been doing that while sitting on the shelf. I never use old fluid. You may get away with it on the street but I doubt that you will on the track.
