Dumb Question on Brake / Clutch Fluid - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Hey Guys, I have what is likely a dumb question on brake / clutch bleeding. I'm getting ready to do the IMS retrofit, clutch, tranny rebuild and will also be changing out all of the brake pads F/R. I have a motive power bleeder and will be changing / bleeding out all of the old brake fluid. My question: does that take care of clutch bleeding? I doubt it will nor could it be that easy but I figured to throw it out there before diving into the Bentley Manual. Thanks.

The clutch and brake share the same fluid but to in order to bleed the line for the clutch you have to crack open the bleeder on the slave which is on driver side of the trans.

Thanks Adam. That's pretty much what I had figured. If I remember correctly that slave is mounted pretty high up and a pain to get to, oh well.

Here is a photo showing the location of the clutch bleed nipple:

It really is a PITA to get to - its six of one, half a dozen of the other to bleed the clutch with just the rear wheel off, or in addition remove the aluminium plate under the gearbox to make things a lot more accessable.....
My triple jointed neck, wrists and elbows seems not to work as well as they used to a few years ago.......

To bleed the clutch fluid, you need to press down on the clutch pedal while the valve is open. It will sink to the floor and stay there while you're bleeding it. Then just pull it up when you're done.

I agree on the placement of the slave cylinder bleeder valve; it is a PITA to get to. Creative use of wrenches and extensions finally got to the the point where I could actually open the bleeder...then the bleed line popped off and I spilled a tad of fluid!

At least my tranny got a good cleaning afterward and I was comfortable knowing the fluids were fresh.

The "hot lick" to do the clutch bleeder is a short or stubby six point double box wrench about 3-4" in length. Mine is a Craftsman that is about 20 years old, but others make them. The short double boxes fit in the limited area and make bleeding the clutch a snap.

Another poster mentioned it as well, but you need to hold the pedal on the floor while bleeding the clutch. We use an adjustable hood prop to hold the pedal so that it remains a "one person" project............

I think their slacking. It took 23H 40M for complete closure of the issue. We may have to step up the training. Spring tune ups and setups are coming. We'll need answers in half that time.
