NOTE: If brake fluid spills on any painted surface, wash or otherwise remove it completely.
  1. PERFORM ACCUMULATOR ZERO DOWN  (See BLEEDING )

    1. Remove the 2 ABS motor relays with the ignition switch off in order to disable brake control.
      NOTE: If the pump motor operates while air remains inside the brake reservoir tube No.1 hose, air will enter the actuator, and this will make bleeding the brakes more difficult.
