Could be there is still an air bubble in the slave. My bleed nipple felt the same as you describe. It would be easy now that you have pedal to back out the slave bolts and then push the slave against the rod while releasing the nipple. This may get that last little bubble out. Or not.

 

Hi my guess is thstb the slve cylinder is going bad to see unbolt it from the clutch bell housing and look for a seeping/leakaround the pushrod, if you change the slave try to clamp the flex line with a set of vice grips not too hard so you wont lose the fluid

 

I'm not sure how bleeding the brake system helps the clutch other than the placebo effect. The creamy stuff is not good; probably a lot of moisture in the system that allows Mr. Corrosion to do his nasty stuff to the hydraulics. The brake fluid being hydroscopic, it attracts water. That's why it is a good idea to flush the system every two years. Easy to skip, I know I tend to procrastinate on this one too.

I use the Racing Blue because it is easy to tell when the old fluid is out and the new in. I also have worn out brake and clutch pumping legs trying to get all the air out of the system. I got a power bleeder from Dave at 928 Specialists and it works like a charm. It is worth the investment if you plan to keep the car and do the maintenance.

If all the air still isn’t out of the system there is the Kempf method of last resort. Others please correct me if I don’t get this quite right; I'm winging it from memory. The idea is that the master cylinder is at a slight upward angle towards the pedal and a small bubble can get caught. The only way to exorcise the bubble is to remove the snap ring at the pushrod side of the master cylinder inside the car and burp the system. I haven’t tried this yet on mine so you may want to research it a bit more or send Jay a PM.

Good luck and let us know how you fix it.

I know several people who eventually resorted to a power sucker; more expensive than a power bleeder but they all reported success.
You just attach it to the bleed nipple and pull the fluid through until it looks good.
Also no risk of blowing off the blue hose; although I am not sure if this is really a risk with a power bleeder.

Hi you can blow the master cylinder resivour off the mater cylinder, if you use too much pressure we use from 10 to 14 psi to pressurize the system for power bleeding, also to consider is the fact that if your feed line to the clutch slave is not in good conditon then there is also a risk of blowing that line off of the resivour as well
