Relocating clutch slave bleeder on a 993
It seems one needs:
Total parts cost about $50 to make bleeding the system not require a torturous jack stand, on your back job.
I have ordered the parts and the next time I have my car on a lift I will have this kit installed.
- A steel M6 to AN3 male-to-male adapter from eBay to adapt the bleeder port on the cylinder to a brake hose fitting.
- A braided 36" AN-3 Brake line with a 90 degree fitting on one end from eBay to run the bleeder port to a more convenient remote location.
- A remote brake bleed kit from Summit Racing: https://www.summitracing.com/parts/rus-641370
to provide the termination needed for mounting the bleeder screw to the remote location.

My idea isn't original just a help with sorting parts. Here is the original posting I got the idea from:
https://rennlist.com/forums/993-foru...eed-setup.html
I plan to use this kit with my Motive pressure bleeder. I see no reason why it wouldn't work.

Just as a suggestion; since the car has to be up on jack stands to bleed the brakes, why not relocate the slave clutch bleed to an easily accessible location while bleeding the driver side rear brake?

Re: Remote Clutch Slave Cylinder Bleed
O.K. Going to show my ignorance (or stupidity) by asking: "Why should it matter if the bleeder valve is lower than the slave cylinder any more than bleeding a caliper?" As long as the system is closed, no air can get in and, when under positive pressure from the Motive Bleeder, no air gets in.

Don't get me wrong, Andreas; I understand and would tend to concur with your logic regarding braking systems and gravity...Hovever, under positive pressure from a Motive Power bleeder, how would it make a difference?
Is the brake master location in the pedal box, higher or lower than the calipers or clutch slave?

^ My thinking, while lacking in technical merit, was simple: brake bleed nipples are located at the highest point of a caliper. Locating the clutch slave bleeder at the same height as stock (or higher) made sense to me.
Air bubbles will rise in a system. I've used a Motive for 12 years (dry) and have always had a super firm brake pedal and a smooth clutch.
If my rationale is silly, let me know.

...But for a fluid change, where a solid system and firm pedal exist, I dont think it matters.
HOWEVER, your engineering rationale is once again based upon worst case scenario, which is as solid as it gets and why would you want things any other way!
P.S. I have a buddy who is a long time race bread Ducati mechanic who does nothing but MF Ducati engineers who in their infinite (or is it finite) wisdom, have now decided that rear brake caliper bleed nipples should be located at the bottom of the caliper.
For rear brake bleeding purposes, he has to remove the rear caliper, reattach it upside down, bleed the system and then reinstall the caliper in it's correct orientation..Italian engineering brilliance, at its best!

To add credibility to my hypothesis, I'll repeat a solution I offered some time ago should air get into the slave cylinder circuit:
Open the reservoir cap, then attach tubing to a left rear caliper bleed nipple and the other end of the tubing to the slave cylinder bleed nipple. Open both bleed nipples, then gently press on the brake pedal. Close both nipples. Repeat if necessary. What you have just done is a "reverse bleed", namely forcing brake fluid and any air bubbles in the slave cylinder line upward to the reservoir.

Let's put this in the simplest rational. Guys like me are tired of (or no longer able to do so) bending, or being uncomfortable on their backs, and just wanna let gravity, and sense do most of the work. I'll do this, as soon as my back loosens up. :-)

I hear ya, Overboosted and this is exactly why I have my eye on a mid-rise lift!
