I had my clutchmasters stage1 and jwt flywheel put in last week. Ever since, the clutch pedal's firmness and travel will deteriorate over time.

When the car is cold cranked, everything is fine. If I get stuck in excessive traffic during my commute, the pedal will start to get mushy. It gets worse and worse, until the pedal will not fully return. It will return to about th emid way point. It's important to note here that the clutch is fully disengaged at this point; the car revs and drives fine. This is not the same behavior as the typical "stuck clutch" that every one experiences.

At first, I thought I might have to bleed the slave cylinder line. The second time it happened, I cycled the clutch pedal in/out multiple times, and it returned to normal(like cycling one's brakes). However, that hasn't worked since then.

So, do I have air trapped in the line? What could it be? It seems to be heat related, but what exactly does that mean? I've got the stock headers, and I'm still on the stock fluid too, with 27k miles.

 

Did you bleed the line for air?

 

I just checked. The fluid is fine. There is no air in the line. And the fluid has not deteriorated. So, the fluid's out. That means its a mechanical issue. I was careful during the break-in process. Ideas?

 

who did your install?

 

Crown. $400, which is about $100 less than anyone else quoted me. And I got a loaner.

 

haha, no kidding, i would never had guessed they would do it. i hate that place.

 

Try one of our carbon kevlar clutch lines, rebleed the system, and this issue should go away. They are $50 shipped from us, and we have plenty in stock.

Worst case, your clutch master cylinder is taking a dump, and that heavier clutch is making the issue worse. Mine went bad a few thousand miles ago as well.

 

how could you tell the stock fluid is not deteriorated? Clutch and brake fluid should be changed annually, as they are hygroscopic (absorbs water)

 

New fluid and SS line ---excellent but also with Hydr clutch systems --Bleed initially then again after a day or two after some use---Theres always a little more air that finds its way to the high point of the slave cyl.
True also what Sharif said ---New Clutch assy and old Master/Slave is a gamble
