Hydraulic System



The following procedure is recommended for bleeding the clutch hydraulic system installed on the vehicle. It is recommended that the original clutch tube, with quick-connect fitting be replaced when servicing the hydraulic system, because air can be trapped in the quick-connect fitting and prevent complete bleeding of the system. The replacement tube does not include a quick-connect fitting.

  1. Before servicing the vehicle, refer to the Precautions Section.
  3. Clean the dirt and grease from the dust cap.
  5. Remove the cap and diaphragm and fill the reservoir to the top with approved brake fluid C6AZ-19542-AA or BA, (ESA-M6C25-A).
    To keep brake fluid from entering the clutch housing, route a suitable rubber tube of appropriate inside diameter from the bleed screw to a container.

  7. Loosen the bleed screw, located in the slave cylinder body, next to the inlet connection. Fluid will now begin to move from the master cylinder down the tube to the slave cylinder.
    The reservoir must be kept full at all times during the bleeding operation, to ensure no additional air enters the system.

  9. Observe the bleed screw outlet. When the slave cylinder is full, a steady stream of fluid will flow from the outlet port. Tighten the bleed screw.
  11. Depress the clutch pedal to the floor and hold for 1-2 seconds. Release the pedal as rapidly as possible. The pedal must be released completely. Pause for 1-2 seconds. Repeat 10 times.
  13. Check the fluid level in the reservoir. The fluid should be level with the step when the diaphragm is removed.
  15. Hold the pedal to the floor, slightly open the bleed screw to allow any additional air to escape. Close the bleed screw, then release the pedal.
  17. Check the fluid in the reservoir. The hydraulic system should now be fully bled, and should actuate the clutch.
  19. Check the vehicle by starting, pushing the clutch pedal to the floor and selecting reverse gear. There should be no grating of gears. If there is, and the hydraulic system still contains air; repeat the bleeding procedure.
