Ok, bleeding these systems can be a little tricky sometimes.
Loosen the bleed screw, located in the slave cylinder body, next to the inlet connection. Attach a rubber hose to it and put the othere end in a container. Now fill the master cylinder reservoir. Fluid will now begin to move from the master cylinder down the tube to the slave cylinder.
When the slave is full, a steady stream of fluid will come from the slave outlet via the hose. 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.
Repeat pumping the brake at least five times.
Hold the pedal to the floor, crack open the bleed screw to allow any additional air to escape. Close the bleed screw, then release the pedal.
