    Object Number: 1251796  Size: SH
  1. Apply the parking brake.
  2. Run the engine at idle speed.
  3. While you move the shift lever into the reverse position, depress the clutch pedal slowly and measure the distance between the point when gear noise is not heard and the point the clutch pedal is completely depressed. The distance should be 30-35 mm (1.2-1.4 in).
  4. If the distance is not within the specified value, check the following:
  5. • Clutch pedal height
    • Clutch pedal play
    • Air in the system
    • Clutch cover and disc pressure plate

Air Bleeding

Notice: Do not reuse the fluid that has been bled from a system in order to fill the clutch master cylinder reservoir for the following reasons:

  1. The fluid may be aerated
  2. The fluid may be contaminated
  3. The fluid may contain too much moisture

Bleed the hydraulic system to remove the air which entered when the pipes were disconnected for repairs. The clutch/brake fluid in the clutch/brake reservoir must be maintained at the MIN level or higher during air bleeding.

  1. Attach a vinyl hose to the bleeder plug. Place the other end of the vinyl tube in a glass container half-filled with brake fluid.
  2. Slowly pump the clutch pedal several times
  3. While you press the clutch pedal, loosen the bleeder screw until the fluid starts to run out. Close the bleeder screw.
  4. Repeat step 3 until there are no air bubbles in the fluid.
  5. Fill the reservoir with brake fluid up to the MAX level.
