Well, I just drove my car this morning and the brakes aren't working. It feels as if the rear disk brakes grab a little, but the front ones not at all. The brake light is on all the time in the car. Brakes usually go slowly, not all at once all of a sudden. It has to be a fluid problem, but what. There is pressure on the brake pedal and the brake fluid level is fine. Anyone else experienced any problems like this?
