Clutch Pressure

Herb Hoover · 11-12-2018, 09:29 AM

Hey all, posted a while back that I was having clutch issues with the pedal sticking to the floor with no pressure. This has been resolved by replacing the CMC. The problem is now that the clutch will randomly lose some pressure and engage at different heights while driving. I can rebuild pressure by pumping it a few times and it goes back to normal for a bit before i starts to slowly lose pressure again. I am not sure if there may be some sort of slow leak or if the system just has a bit of air and needs another bleed. Any help on this would be great!

Did you replace the CSC as well or get the CSC elimination kit? That’s the common failure on our cars and can have similar symptoms.

Sounds like there is still air in the system. But it's possible that either the slave or master (yes, again) could be the culprit. It is highly recommended you look into replacing the CSC before it fails on the street and strands you somewhere.

I have the CSC but we were trying to avoid dropping everything to do it at this current time. Reason being is that I am looking to get the CSC delete next spring.

You have air still in the system. Eventually your CSC will fail replace it before it’s too late. The only question is when will your CSC fail than if your CSC will fail. Install the Z Speed Performance CMAK kit as soon as possible.

You do realize that there are other options on the market other than that, right?

Sounds like you still have air in the system. The most likely spot is near the CMC. Break the connection there and bleed there first. Then at the CSC.
