Thanks rao, I figured it would be pretty similar to bleeding the brakes. But when you push the clutch pedal down, it pushes against the clutch lever and releases the clutch, then when you open the bleed valve, the clutch lever pushes the slave cylinder back in. You now have your clutch engaged with your foot to the floor. I'm concerned that the clutch master cylinder will stay down and you will be SOL. I guess it comes down to the design of the clutch master cylinder. If there is an internal return spring it will probably come back on it's own and take another "gulp" of fluid from the reservoir to allow you to continue bleeding the system.
Anybody have an exploded diagram of the '99 RS clutch master cylinder?
