Pressure Bleeding

  1. Discharge system pressure. With ignition off, pump brake pedal a MINIMUM of 40 times with complete pedal strokes. Brake pedal will feel hard when accumulator is completely discharged.
    CAUTION: Once system is depressurized, DO NOT turn ignition on until all service operations have been completed.
  2. Remove reservoir cap. Attach Bleeder Adapter (J-37115) to reservoir. Attach bleeding equipment and pressurize system to 10 psi (.7 kg/cm2 ) for 30 seconds. Slowly increase pressure to 35 psi (2.5 kg/cm2 ).
  3. Attach a clear hose to bleeder valve and submerge other end of hose in a container of clean brake fluid. Bleeding sequence is as follows: right rear, left rear, right front and left front.
  4. Starting at right rear, open bleeder valve. Allow fluid to flow until no air is seen in hose. Close bleeder valve. Repeat procedure for other bleeder valves. Fill fluid reservoir.
