Clutch Pedal Sticking - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I know this has been cover many times probably. I did a search and found some threads about this issue, but none pretain to mine.

The Trans shifts fine, no grinding at all. The clutch does not stick at all while driving like some. What i noticed is that when it gets really hot outside and i press the pedal in to start the car, the pedal when pressed in stays in, until i kick it, then it comes back.

The pedal feels very soft, and I have to pump the pedal a few times, then it starts to bulid up pressure. Then the issue goes away and it drives Fine. So im thinking maybe the rubber line is expanding, when it gets really hot out?

What can i do you fix this issue?

TIA

i wanna say it's prolly your clutch line.

i remember on my buddies Z, when he first put on his turbonetics kits his clutch line would get super hot and the clutch would stick to floor... check it...

prolly just air in the lines...

this happened to my bro all we did was change out clutch master cylinder we didnt change tha slave cause everytime he pressed the clutch the slave would move in and out try that if not bleed master cylinder then bleed that box "follow master cylinder hard line cant miss it" after that bleed slave that should fully take out any air with in clutch system hopefully if you did it right

Im going to replace the line with an Earls Braided line and then i'll bleed the clutch. So if the rubber line and the chance that there maybe air in the system will be taken care of hopefully.

I also noticed that the Slave overflow line has a small tear in it. Could that be the problem? Nothing is leaking though.

S-Nation S13 · 06-30-2008, 11:15 AM

your best bet would be to change any line that you think might have a small/hairline crack although now may not cause a problem now but overtime i bet it will depends on how much wrench time you wanna put in

bleeding system like i posted earlier in that oder should move air from high point "clutch master" to lowest point "slave" idk if adjusting clutch pedal would help but ill look into it pm me anymore info you have

just peel the dust boot on your slave a tad bit, you might see some fluid. if you do, its most likely leaking. replace and you should be fine.

definetly start with the free fix's first! like bleeding the lines from the slave. I had some problems with a line attached to the proportioning valve. I just removed that line and now it's just a straight hard line from the master to the slave with no problems at all! another thing is make sure you are bleeding them correctly or you will just suck alot of air back in.

Erjay1 · 06-30-2008, 11:46 AM

You need a stainless steel clutch line. Right now the rubber line gets hot and expands. Stainless steel wont do that. Thats it.

dubmasterdee · 06-30-2008, 11:49 AM

it can be your master... my does that and it's the master cyinder... check the master and the slave for leaks
