    Intermittent brake fluid light on cluster

    Often when I'm braking the brake fluid lights flickers for a bit when I'm taking corners. I checked the level and it's in good shape, so I'm thinking it might be a faulty sensor? Is the body roll causing the fluid to swish around and think it's running dry? This only happens when i'm going around corners.

    Thanks for any tips!

    EDIT- Topping off the brake fluid was the fix. I simply filled it up near the top and my issue went away.

    If the fluid is at the max fill line then it should not trigger the sensor even if you take a hard corner.

      Good shape meaning....


      Mine was just a hair under full and it would do this. I added a little more and it went away.

        I had the same problem, it was about 1/2 way between min & max, once I filled it up to max the problem went away.

              If you verified your level is at the max and you aren't losing fluid, then look into getting a new reservoir cap.
