Open the cap to the brake fluid reservoir on the master cylinder and check the level of the fluid inside. The fluid should reach the full line on the reservoir. If it doesn't, add fluid to it to ensure there is enough to keep the system from sucking air in as you bleed it. It's okay if you overfill the reservoir, as you will be draining a good amount of fluid from the system in the bleeding process. The slave cylinder in your vehicle should be located in close proximity to the transmission, though its exact mounting location will vary from application to application. You will find the bleed screw on the bottom or the underside of the slave cylinder. It looks like a bolt with a nozzle sticking out of it. If you have difficulty locating the slave cylinder or bleed screw, refer to the service manual for your vehicle. Press a clear hose onto the slave cylinder bleed screw and place the other end in an empty soda bottle. This will control the direction the released brake fluid will travel in as you bleed the system and provide a container to catch it in. Ensure the hose is securely pressed onto the nozzle. Set the soda bottle down on a flat surface like the ground or a box to ensure it doesn't tip over. Use an open ended wrench to turn the bleed screw counter clockwise with the hose attached to it. This will open the system and allow fluid to be pressed through into the hose. Be sure to leave the hose attached to the nozzle at all times to avoid spilling brake fluid. Leave the screw open for now. With the bleed screw open and the hose in place, have a friend press the clutch pedal down to the floor and hold it there. It is extremely important that your friend not let the pedal release until you close the bleed screw, so be sure you tell them so. As your friend presses the pedal downward, brake fluid will be drained into the bottle through the hose on the bleed screw. Make sure you are positioned so you can see the fluid draining through the hose. With your friend pressing the clutch pedal to the floor, use the open ended wrench to turn the bleed screw clockwise to tighten it again. This will once again seal the hydraulic clutch system, preventing air from getting sucked back into the system through the bleed screw. If your friend releases the pedal before you close the bleed screw, air will be sucked into the system, making the bleeding process significantly longer. Don't overtighten the bleed screw, as you will need to open and close it repeatedly. With the bleed screw closed, have your friend release the clutch pedal. Once the pedal is all the way back to the top of its clutch throw, you can begin the bleeding process once again to remove the remainder of the air bubbles in the system. Be sure the pedal has been released completely before you open the bleed valve again.
