Clutch Bleeding


1. Inspect and fill clutch master cylinder reservoir with appropriate hydraulic oil. You will want to check this during the bleeding process making sure it doesn’t run out or you will get air into the system again. Leave cap off of reservoir.

2. Have your friend camp in the drivers seat to push in and let out the clutch pedal when you tell him to.

3. During this procedure DO NOT allow your friend to “pump” the clutch pedal.

4. You will be opening and closing the bleed screw on the slave cylinder as instructed below. CAUTION: During this procedure protect your eyes from squirting brake fluid by using a small hose and a soda bottle. Brake fluid is nasty stuff so wear gloves.

5. (Helper) Press clutch pedal in fully and hold.

6. (You) Open the bleed screw to allow fluid to escape.

7. (You) Close bleed screw quickly.

8. (Helper) Release pedal completely

9. (You) Top off fluid in reservoir. Leave cap off of reservoir.

10. Repeat steps #6 – #9 no less than 10 times before going to #12 below. NO PUMPING!

11. Now you will want to purge the slave cylinder of any air bubbles that might be trapped inside of it.

12. Grab the clutch fork and push towards the slave cylinder pushing the rod all of the way into the slave cylinder as far as it will go AND HOLD it in.

13. (You) open bleed valve and command helper to push the clutch down slowly purging any air that was trapped in the slave cylinder

14. (Helper) As soon as the pedal hits the floor command your bleeder monkey to close the valve before you let the pedal return from the floor.

15. Repeat steps #6 – #9 one last time and proceed to the clutch reality check.


The easiest way to do the reality check of the clutch is to get all four tires in the air by placing the car on a hoist.

1. Start the engine and put the car into 1st gear.

2. Slowly let the clutch out until the wheels start to turn round and round.

3. Now slowly push the clutch in until the wheel stop turning. Hold the clutch at this position.

4. At this point the clutch pedal should be at least 2-3 inches off the carpet. If not then the clutch needs adjustment and/or the clutch needs to be inspected for issues that are causing it not to release fully.

The reason why the clutch should be this far off the floor at the engagement point is to allow enough room for movement of the clutch disc so it finds a nice center position between the flywheel and pressure plate. While this may be a tedious method to make sure clutch is functioning properly but this is the preferred method and the true reality check for where the clutch releases.
