Soft Clutch Anyone? HELP!!!
 

While I'm driving around town my clutch pedal feels nice and tight BUT if i've been on the interstate for a while my clutch pedal gets really soft. I can push it in and sometimes it will even stick. I can pull on it with my foot and it will spring back into place. What I have been doing is putting the car into neutral and while coasting along i'll pump the clutch 3 or 4 times and the "tightness" come back like i've been in town driving. It still allows me to change gears if necessary when it's soft but not sure what I should do.


Is there such a place to check a clutch fluid level? I may get flamed for that question but I honestly do not know.

Thanks ahead for all your answers.

Well crap! Not sure where to start after reading the above post. My car is an 09 Nismo with 38k on it i'm the 3rd owner of the vehicle and have no idea if it is under warranty.

Also where can I check the clutch fluid level?

And if I have to bleed the clutch how do I do this?

Would this be under the power train warranty because that's 5yrs 60k miles.

The transmission should be covered under the powertrain as long as the part isn't something that wears, like the clutch itself. The clutch fluid reservoir is next to the brake reservoir...to the upper right (driver's side) if you're facing the engine from the front.

My buddy Windex just had this happen to his Z, Nissan said it was not covered under warranty. Technically speaking, it's part of the transmission case, which is not the transmission itself.

They called it a "wear" item.

boy oh boy this just keeps getting better and better. My guess before reading all of this was maybe fluid was a little low and that by adding more it would resolve I sure hope so. My car fax report said that the first owner replaced the clutch master cylinoid under warranty so I'm hoping it's not the same problem returning. :ugh2:

Just as a reference, I have 35k miles on my car and about 15k miles ago I did the Z1 SS clutch line and filled with Motul RBF 600. I've tracked my car and drifted it without any issues.

I did notice that after the track days the clutch pedal would be weird for a day or so after, then it would go back to normal. Not sure why, but when I drive the car hard, the pedal certainly feels different. I've never had it completely lose pressure though.

Once I bled it properly it has worked fine since.

Is the process for bleeding the lines a huge pain in the A$$?

Not really. I had a buddy and a lift so it wasn't too bad for me.

I'm so car illiterate. I wouldn't even know where to begin. I'll have to look up some how to videos or something maybe youtube

I would just find a good tuning shop and save yourself the headache if you don't know what you're doing. Watch them to see how it's done and do it yourself next time if it's within your limits.

He has something to jack up the entire car. His buddy is sitting in the car to pump the fluid out via clutch pedal while he has a tool to keep from air going into the lines.

Air into line = no good.

Go search youtube yourself. Just type bleeding clutch fluid or brake fluid. Same concept.


Unless the shop use a vacuum system ^_^;;;

When I look under the Brake fluid cover to the upper right I find 2 reservoir's one is bigger than the other but both caps say something about brake fluid. Does the clutch use the same fluid as the brakes? and if so which reservoir would be for the clutch the larger or smaller one.
