Bleeding clutch slave??

[BYprodriver]

I disconnected the clutch fluid line at the transaxle to give more room for leftside axle removal on my 2000 S , replaced everything bled according to Bentley manual but clutch pedal still does nothing, slams to the floor. Any ideas what could be wrong??

sounds like you did not have the clutch pedal depressed when you bled the line. It needs to be depressed the entire time while bleeding the clutch line to open the master cylinder. Once you've finished bleeding, you'll need to manually pull the clutch pedal back up as it won't return on it's own the first time.

You could have a bad master cylinder but I think you have lots of air in the line (caused by not depressing the clutch pedal for the bleed).

I bled with pedal up & down with no result, never had any problem with pedal/clutch before disconnecting the line & now fluid is clean & air free after runing a pint of new fluid thru. My 2000 S does have 85,000 miles thou

Must of had a pocket of trapped air in the slave cyl. I upped the pressure on the bleeder to 28PSI & farted out the hiding air. Got 3" of pedal travel. Drove the car 3-4 miles & the pedal returned to max height

for the DIY to bleed a clutch slave with no shop equipment can be impossible sometimes.
Here is a sure fire way to do it with out a power bleeder.

1. run a clear plastic line from a rear brake caliper bleeder to the clutch slave bleeder.
2. be sure the brake master is full of fluid
3. have someone depress the brake pedal and hold it, not to hard but hard enough to keep it depressed
4. while they are holding the brake firm open the bleeder for the caliper and now open the bleeder for the clutch slave
5. the brake pedal will go down and stop, air will bubble up into the clutch master reservoir
6. close the caliper bleeder and refill the brake reservoir
7. do the same procedure again, depress brake and hold, open bleeder and push fluid through clutch system in reverse
8. do this for 5 or so times, each time keeping brake master cylinder full
9. in essence you are reverse bleeding the clutch system

Why bother with all the in-between stuff?

Why not just reverse bleed it directly from the power bleeder to the slave bleed nipple and extract any excess fluid from the MC with a Turkey Baster?

This way you totally eliminate the possibility of introducing air into the brake system because you're not opening the brake master cylinder at all. They are two distinct systems.

Both the clutch and the brakes have their own separate master cylinders, the clutch master is low, behind the firewall opposite the clutch pedal. They only share a common fluid reservoir.

Technically you are correct.
However, I am under the assumption a DIY (do it yourselfer) would not have access to a power bleeder. This is a simple work around.
