clutch pedal issues?

xgrudgex · 01-15-2011, 08:55 PM

Just today I had some issues when shifting at highway speeds, just wanted to see if anyone else had any of the same issues?
Well basically I was driving in 5th gear thru slow traffic... about 15 minutes(I'm in cali lol)
And when speed picked up I went to shift but I had about 6 inches of dead pedal and the last inch I had pressure.... wtf!?
So I popped it in neutral and tried hitting the clutch repeatedly to maybe build the pressure up but no go, pulled over, after about a minute of ddriving thru the streets it came back!
So fluids are good, belts tight, the only thing I'm low on is window piss so I'm confues:/ any ideas or anyone else have a similar issue?

Why were you in 5th? Should be 3rd and lowerfor slow traffic... creeping traffic I only use 1st.

It sounds like your clutch fluid need replacing.
The soft pedal condition can happen if you have air in the system or if the fluid is past it's boiling point and that can cause the symptoms you've described. Sometimes if the clutch fluid has absorbed water or seen too much heat once too often, the boiling point of the fluid drops dramatically and will start to vaporize in the line and lose the hydraulic properties of the fluids. The best recourse is to flush and replace the clutch fluid with a quality brake fluid with a higher boiling point. Clutch fluid is the same stuff as brake fluid, if you were wondering.

Hope that helps

Always someone on here trying to make someone look stupid... I was actualy coasting in "slower" than what highway speed... not 35 mph it was speed up and slow down from 45-60 which I feel 5th gear was appropriate. But thanks for trying to explain how I should drive my car

As for the issue it was the brake booster.... so they say which makes sense since all fluids were where they should be, I dont think it was a leak just more of a malfunction, either way sucks for me since I will be paying out of pocket for it since I am past the 35k mile coverage.... lameeeee

I just got the same issue, clutch paddle lost pressure. I started to notice the clutch felt very soft for the first half and the engagement point felt like it had shifted to the bottom. Yesterday, the while driving on freeway and coming to traffic stop the clutch paddle got stuck to the floor when I down-shifted. The problem seemed very apparent on freeway, and less for local driving. I when to the dealership and 2 hours later they said they have to replace the Master and Slave clutch cylinders per Nissan Tech Support.

hold on, why would the brake booster affect the clutch? they are not connected in any way. if the brake booster failed, it will be your brake pedal that will feel different, and it will be harder, not softer.

I've had the same thing since day one. I always thought it was normal...my clutch only engages 2 inches from the top and the rest doesn't do anything. I don't even depress my clutch all the way because it seems like there is no point. Now I'm paranoid!!!

Thanks. I'll bookmark that page but I actually don't mind the high engagement...just wanted to make sure it wasn't affecting or damaging anything.

If I were to go through the process and lower my engagement point, if I had experined the above issue xgrudgex experiences, do I risk damage to the clutch? would it not fully disengage?

RockStarKick · 01-27-2011, 02:38 PM

I would think not.. As long as you make sure that the clutch is fully engaging/disengaging.

I personally like the engagement point of my clutch, it engages about 40% from the floor.

CrownR426 · 01-27-2011, 02:49 PM

The first winter I had my car I was on my way back from the mall and my clutch pedal was stuck to the floor. I was scared because I was in traffic. Stalled my car and got so mad... Turned the car back and and the problem was gone. o____O;; I know I've read a few posts of people saying the same. I should've gone to my dealer the next day for service.

Thanks. My engagement point is a little on the high side; I just want to lower it some, maybe 1 turn....

cheshirecat · 01-28-2011, 11:08 AM

IMO, this sounds like hot/boiling clutch fluid, not an engagement point issue.

Change out the fluid to a DOT4 blend like Motul RBF600. You may also want to consider upgrading to a stainless steel clutch line. Neither of these are expensive and the install is very straightforward. The biggest pain in the *** is just getting the air out of the system once it's installed.
