Hello,

So i live in phx and it gets ****ing hot in the summer. Even with regular bleeding of my clutch fluid, i am sometimes still plagued by the "sticky clutch pedal" issue.

From reading the posts, it is caused when the brake fluid in the clutch system gets to hot and boils. Does anyone make a cooler for this? I know nismo makes a power steering cooler. Could that be modified and used on the clutch fluid instead?

here is the nismo unit

don't flame me if my question is stupid. I want to take the car to the track some day and don't want to worry about this issue there and risk ****ing up my clutch.

thanks
marty

 

Clutch fluid doesn't circulate, so adding that type of cooler won't help.

 

Was contemplating the same thing. Good point Brandon, thanks.

 

Upgrade the clutch fluid?

I know if u see higher temps w brakes, u upgrade the brake fluid to dot 4...

Not sure about the clutch

Or how about putting a better heat shield arount the clutchline to reduce heat soak from the headers

 

I get the 'sticky clutch pedal' problem when the fluid gets old. I flush it completely about every two years, which is when the problem will just start happening again. I don't trust anything other than a complete two person flush done the way specified in the service manual.

I've heard some can't solve the problem without replacing the cylinder, but I can't remember if it was the slave or master that went bad. If I had to guess, it would be the slave.

 

there has to be a way to prevent this from coming back. i have it still happen from time to time even after the fluid change. i live in az and am scared to take my car to the track now.

what about something like this?

You can do 2 things:

#1) wrap the lines with heat shielding tape/material

#2) upgrade the fluid to something with a higher boiling point

Both of these things will help, but I would start with heat wrap/shielding first

 

well, i guess some racing brake fluid is in order and a full bleed of the old stuff

 

don't underestimate the heat shield materials as well. As close as the clutch line runs to the exhaust there is a lot of heat that leeches in.

 

Nismo makes a stainless steel clutch line that comes heat wrapped

 

I had the SS clutch line from Z1 installed by my local wrench last week, they also adjusted my clutch pedal up a lil. So far not one stuck pedal or mushy feel after several hard launches to redline and 100+ temps during my road trip this weekend. Could have found the real fix for my stupid clutch system. I'm boosted with a recently installed JWT clutch and flywheel combo as well, and had a bleed and flush done after it was installed. Hope this helps guys.

 

I have forged performance ss clutch line. it is wrapped in some sort of heat wrap, $50..definitely recommended. just did a vegas summer and had no issues with it.
