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.
- Before servicing the vehicle, refer to the precautions in the beginning
of this section.
- Clean the dirt and grease from the dust cap.
- Remove the cap and diaphragm and fill the reservoir to the top with approved
brake fluid C6AZ-19542-AA or BA, (ESA-M6C25-A).
NOTE: 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.
- 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.
NOTE: The reservoir must be kept full at all times during
the bleeding operation, to ensure no additional air enters the system.
- 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.
- 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.
- Check the fluid level in the reservoir. The fluid should be level with the
step when the diaphragm is removed.
- 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.
- Check the fluid in the reservoir. The hydraulic system should now be fully
bled, and should actuate the clutch.
- 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.
