How to Bleed the Clutch Slave Cylinder on a 1993 Mazda 626

Bleeding the clutch slave cylinder on a Mazda 626 is necessary to improve the performance of your clutch system.

The clutch in a car equipped with a manual transmission system can sometimes stop working properly. The clutch pedal may weaken and not engage or disengage properly, much like the brake pedal in a car. When this happens, it is necessary to bleed the clutch slave cylinder; this will tighten the clutch pedal and ensure proper performance. It is helpful to ask a second person to help you bleed the clutch, as one person will need to depress the clutch pedal while the other person works in the engine bay area.

Things You'll Need

• Set of automotive line wrenches
• 1 quart jar (or bottle)
• Bleeder hose

Instructions

1. Locate the clutch release cylinder under the hood of the car. Pull off the rubber cap from the bleeder screw.

2. Attach the bleeder tube over the end of the bleeder screw. Push the tube in to secure it tightly and to guarantee a vacuum seal.

3. Fill the jar halfway with hydraulic brake fluid. Place the free end of the bleeder tube into the brake fluid.

4. Press the clutch pedal to the floor and release it slowly to the original position. Repeat this process several times.

5. Hold the clutch pedal to the floor; at the same time, use a line wrench to loosen the bleeder screw until the brake fluid begins to run out into the jar, then close the clutch cylinder bleeder screw. Repeat this step several times while watching the fluid in the jar for air bubbles. (This step works best with the help of your assistant, who can watch out for the air bubbles while you press on the clutch.)

6. Close the bleeder screw when the air bubbles have stopped forming in the jar.

7. Reattach the rubber cap to the tip of the bleeder screw.
