DURING A PANIC STOP THE BRAKE SYSTEM LIGHT CAME ON AND THE BRAKES FELT SOFT BUT STILL WORKED. DURING THE DRIVE THE BRAKES BECAME VERY WEAK. WHEN I CHECKED THE BRAKE FLUID IT WAS EMPTY. I REFILLED IT AND STARTED CHECKING FOR LEAKS. I FOUND THAT BOTH THE FRONT AND REAR BRAKE LINES WE FRACTURED BECAUSE OF THE PRESSURE DURING THE PANIC STOP CAUSING THE RUSTED LINES TO BURST.
