The "Brake System" light comes on to warn you of low pressure in the lines. In my experience, when this light starts flickering on and off, you've either got a bad master cylinder, leaking brake line/hose (the rubber hoses to the front calipers are most susceptible), or bad rear wheel cylinder. You mentioned that you've replace the master cylinder. Was it new or rebuilt? I've had premature failure from rebuilt units. And if the fluid level is staying the same, a failed master cylinder would be a likely culprit. Good luck! Elijah __________________________________________________ Do You Yahoo!?
