### Hydraulic Clutch System

#### BLEEDING

Fig. 1: Clutch system bleeding points — Altima, Maxima, 240SX and 300ZX

Bleeding is required to remove air trapped in the hydraulic system. The bleed screw is located on the clutch slave (operating) cylinder.

Some models are also equipped with a clutch damper mechanism. The clutch damper mechanism is bled in exactly the same manner as the operating cylinder. It should be bled along with the operating cylinder.

1. Remove the bleed screw dust cap.
2. Attach a transparent vinyl tube to the bleed screw, immersing the free end in a clean container of clean brake fluid.
3. Fill the master cylinder with the proper fluid.
4. Open the bleed screw about 3⁄4 turn.
5. Depress the clutch pedal quickly. Hold it down. Have an assistant tighten the bleed screw. Allow the pedal to return slowly.
6. Repeat the above procedure until no more air bubbles are seen in the fluid container.
7. Remove the bleed tube.
8. Replace the dust cap and refill the master cylinder.
9. Bleed the clutch damper, if equipped.
