Will this CMAK kit include everything to get it running and put an end to these CSC issues?

CMAK includes everything you need,
Is the clutch worn out? Miles? The only reason the slave usually gives up is if the clutch is past its life span and at that time will bottom out the slave cylinder, Once it bottoms out it will over heat the bearing and kill it as there is constant pressure on it. You can pull the black boot off the side of the trans and look in with a flash light to see if the slave is pushed back all the way, If it is, the clutch is worn out.

Great to hear that the CMAK will resolve it all. I have approximately 37,000 miles on my southbend stage 2 clutch and flywheel which were replaced at the same time as the CMC and HD CSC. I haven't had a chance to look under the car myself. I will be looking to swap out the CSC with the CMAK kit, and likely a new clutch.

Can you please clarify what you mean by the "HD CSC literally just gave out". Was there a loss of pressure ... loss of fluid? There are a number of us who have switched to the ZSpeed HD CSC who I suspect would be interested in knowing more about what happened. The HD CSC is generally regarded as being bullet-proof and a big improvement over the stock OEM CSC. Failure of the HD CSC is rare based on my understanding. If you could share more details ... mileage on the CSC, driving habits, clutch fluid change interval during the 3 years, etc., it would be helpful. Thanks!

When I said it gave out, I meant there was an instantaneous loss in pressure. Fluid is now near empty. After swapping out to the HD CSC and a new CMC, I shortly encountered inconsistent pressure from my pedal after every few thousand miles of driving, and I would bleed the fluids, but similar symptoms would reoccur as miles accumulated on the fluid(especially during stop and go traffic in the heat). After contacting Joe, he informed me that it could be the CMC. His advice was 100% correct and greatly appreciated. I swapped it to the RJM CMC 8,000 miles ago with fresh RBF 600 fluid. It resolved all issues. Then two nights ago while driving on a cool night, the clutch went from full pressure to 10%, and shortly to the inability to shift into gears.

-37,000/ 3 years on the HD CSC
-Changed every 7,000 miles to Fresh Fluids because I didn't know why it was acting up until I consulted with Joe.
-Swapped out CMC at last 8,000 miles (everything was great)
-Drive in a lot of stop and go traffic, seldom redlining the car. Car is now at 100k miles.

Hope this helps. I'm happy Joe has created a new kit, and I'm very glad it's external so no more dropping the transmission for a while.

OK, thanks for your response. It's interesting since I have the same set-up, with the ZSpeed HD CSC and RJM CMC. No problems after 5K miles, but your post is a bit concerning. Have you confirmed that the HD CSC failed and not the RJM CMC? Also, did you install the ZSpeed insulated clutch hose? How about the RJM clutch pedal assembly?

Yes, It works fine with all single mass flywheel / single disk clutch kits, Only thing it is not set up to work with yet is the OS Giken Twin and Triple disk clutches.
