Can I Prevent CSC Failure

Spooler · 08-25-2014, 09:51 PM

The only thing you can do is a fluid exchange every 15,000 miles. Even the older cars with the external slave cylinder were hard on fluid. The problem with why the master cylinder goes is due to all of the debris (cooked fluid) ending up in the clutch fluid reservoir. When the CMC may go south is when it is pumped trying to get the clutch back after a CSC failure. If they run dry and are pumped to get the air out, bad ju ju. It is always best to replace them as a set. I have gotten away with only doing the CSC in the older cars many times. If it failed, I could usually make it home as long as I could get the sucker in gear. I wouldn't use the clutch the rest of the way home and prayed for no stops. That is when it get's tricky. I am not sure how these newer cars will react.

True, but IMO the worst thing that can be done, which I bet most people do because of the Z's shitty clutch feel is to hit the pedal to the floor. I bet I can make a CSC fail within 3000 miles if I continuously slammed the pedal to the floor

I don't go all the way to the floor either. The time I am pushing in on the clutch I am shifting out of gear and by mid ways I am in the next gear. It is fast and smooth. I don't sit at a stop light with my foot on the clutch either. I adjust my seat where I have to stretch to go all the way to the floor.

Sorry for the thread revival, but I'm just now reading this and had no idea pressing the clutch to the floor in between shifts was bad for the car! I have been doing this all my life and its hard to break this habit, and is just another thing I have to think about while shifting. Has anyone put some sort of object behind the clutch pedal that will block the clutch pedal from hitting the floor board, allowing the pedal to be fully pressed while not *actually* being fully pressed? Or does the RJW clutch assembly feature an adjusting mechanism such as this?

Thinking about getting the RJW, Z1 SS clutch line and putting in some AP Racing Dot 5.1 in there to buy myself some more time. Any other easy mods that doesn't require taking apart the trans to help delay CSC failure?

I have a question regarding this too.

Is this an issue for all model years, or has it been addressed over the years?

Nissan hasn't done $hit about it. It was a problem in some earlier 350Z's as well until they switched to an external slave cylinder in later models. But they went back to the crappy internal design for the 370Z and haven't changed anything yet.
