the same way you bleed the brakes

Basically the same way you bleed the brakes. On the slave cylinder you will find a bleeder valve . 1 .Attach a small hose or clear plastic tubing over the end of the bleeder valve. 2. Place the other end of the tubing into a clear bottle or jar. 3. Have an assistant press on the clutch and hold in down to the floor. The clutch pedal should remain pressed to the floor. 4. Open the bleeder valve to release the pressure . Make sure that your assistant does not release the pedal pressure on the clutch. It needs to stay pressed onto the floor; otherwise, air will be drawn into the line. You will see fluid and air bubbles rushing out of the valve through the plastic tubing ( if clear tubing isn't available and you are using a small hose place it in clean brake fluid and watch for bubbles ). 5. Close the valve by turning it clockwise until it is tight. The pedal will now have to be raised by hand and pumped once or twice. Repeat steps 3 - 5 until there are no more air bubbles . There are other methods depending on what equipment you have available to you. Make sure the reservoir is full before begining and top off as necessary .
