I put Henry's post in blue and my questions in black.

"1. Check brake fluid level in brake resevoir and, in necessary, top up to maximum level.

draw the brake fluid for fluid coupling (slave cyliner) from the resevoir.

^^Is the above statement just a summary of what is about to follow?^^

2. attach hose to bleed screw of right front caliper and open bleed screw.

3. Have someone else cautiously depress the brake pedal until the hose has filled with brake fluid and there are no more air bubbles to be seen. Prevent fluid from running out of the hose by nipping it.

4. Attach free end of hose to the bleed screw on the extraction cylinder and open bleed screw.

What are they referring to by "extraction cylinder?" Is it just the clutch slave cyl?

5. By alternately depressing the brake pedal and closing the bleed screw of the brake caliper, releasing the brake pedal and opening the bleed screw a number of times, fill the coupling resevoir to the maximum level.

Note; It is recommended to top up the fluid level in thebrake fluid resevoir once during the procedure.

Again, this is confusing because I don't know what the coupling reservoir is. Is it just a container to drain fluid into, is it the slave cyl etc?

6. Close bleed screws on brake caliper and extraction cylinder and disconnect the hose.

(Same confusion continues - don't know what extraction cylinder is)

7. Check the coupling actuating mechanism for the function and leaks by shifting into reverse gear with engine running.

8. Top up brake fluid in resevoir to maximum level."

In summary, what the manual is saying is to first empty the clutch hydraulic system completely.

Where do you empty it into?

Then back fill the system from the bottom until the resevoir is filled.

Is the fluid sucked back in by means of the break hydraulic system by opening up the bleeder on the caliper, releasing the brakes, closing nipple, pressing breaks, etc....?

They suggest using the brake system as a means of doing this. I suppose you could also use a conainer elevated above the car a couple of feet, and use hydrostatic pressure to back fill the system.

Ok, so if you read all this you probably get the idea that basically I need to know the meaning of a couple words and that would probably clear up a lot of things. Any other advice would be appreciated as well.

Thanks

Just spend $45 on a cheap pressure bleader and make your life a lot easier. Pressurize system, open bleed screw and you're done.
