So on my way to work my car made a couple of beeping noises and the brake light in the speedometer flashed a couple of times. But when the system checks itself it says everything is OK.

Any idea why this would happen?

 

Brake fluid. You need more.

 

That's exactly what I was thinking it was, but I wanted to check.

Any recommends on fluid?

 

Either the factory stuff if you're just adding, or make it worthwhile, throw some stainless brake lines on it, and some ATE Superblue fluid. Thats what i'd do anyway.
