Fun Question

Would you use ancient brake fluid thats been stored properly in garage? I have two old cans of fluid with the metal safety seals caps in tact. One newer plastic bottle (previously opened) with the cap on tight!

 

If the unopened containers are under 3 years old you may be okay. Otherwise no on both accounts.

 

Always heard or thought moisture is the issue or contaminent. Is it possible moisture has got in the fluid? Doesn't sound like it.
Not sure I would use in newer car. Brake fluid not real expensive.....

 

Brake fluid is hygroscopic, so yes, once the seal is broken and has been exposed to air it shouldn't be used again, regardless of how tight the lid is on. That being said, there are also the additives in the brake fluid that break down over time (and of course with use). Fixing issues caused by compromised brake fluid is far more expensive than just buying new brake fluid.

 

Thanks for the feedback guys. I’ve had these old cans for years. Knowing that moisture is the main culprit contaminating brake fluid, I just wonder if the cans/bottle are perfectly sealed why would it go bad? Both containers are new and the seals bulge when squeezed. No fluid leaks out.

Just a fun question.

 

This is the only thing that makes me wonder about its usefulness. The chemicals breaking down inside the can. Interesting.
