The low brake fluid warning came on my dash as I tried to stop at a stop sign. I tried again to depress the brake pedal and the brake pedal was not moving. It was like it was locked in place. The second time I tried to push the brake, the warning flashed that I had no brake fluid. I managed to avoid traffic and the treeline, but sailed over a guide sign and into a cluster of power lines. Two of the lines were pulled out of the ground from the force of the impact. I checked the brake fluid reservoir and I do in fact have brake fluid within the specified range. My brakes should have worked.
