Fluids - shelf life

Discussion in 'Technical and Troubleshooting Torque' started by mattb, Apr 7, 2010.

  1. G'day All.

    Do fork oil, and brake fluid, have typical shelf lives?

    I'm changing the fluids in my SR500, and have half a bottle of fork oil which I bought two years ago, and some brake fluid bought a year ago, which would do the job.

  2. Brake fluid absorbs water if not sealed properly, rendering it useless, It will still work as water is not compressable, but it will rust the inside of your lines and cylinders,
    Oil does not go off, but it also needs to be in a sealed container.
  3. The main problem is that water lowers the boiling point.
  4. Depends on how many times youve opened the container. Old fluids will absorb water from the atmosphere everytime you have the cap off, which is why new fluids are best.
  5. Fork oil should be fine, but for the sake of $4, I would buy new brake fluid!
  6. Chuck the brake fluid. I hear it makes good weed killer.
