My brake fluid level light came back on after two days of refilling the fluid. What could be the problem?

Hi,

You have a leak at some point. Have you noticed any wet spots under the vehicle or on the back side of the tires or wheels? Also, the master cylinder could be leaking.

When you refilled it, did you use DOT 4?

Let me know.
