JUST CHANGED REAR DRUMS, PADS AND WHEEL CYLANDERS. THE ABS AND BRAKE LIGHT ON THE DASH STAY ON WHEN I START THE VAN AND GO OFF AFTER ABOUT 2 MINUTES. THE ABS KEEPS RUNNING (NOT PULSING BUT THE HUMMING WHEN THE WYWTEM IS BEING CHECKED) ABOUT EVERY 15 SEC. ALSO WHEN I SHUT THE VAN OFF BRAKE FLUID CAME SPILLING OUT OF THE RESIVOIR..' ANY THOUGHTS??? THANKS IN ADVANCE ED
