Clutch issues

[Tx-Sx-FS]

i replaced the master cylinder and bled the lines, i need to know why the pedal itself isnt popping back like normal....could it be the spring behind the clutch pedal? or is there even a spring back there? i know for sure theres no air in the hydraulics but im thinking that its a spring or something on the actual pedal thats hesitating....like when i try to pop the clutch, it just revs high then the clutch engages, so im thinking theres a weak spring or something....could that be my problem? also why im thinking its a spring because when i push the cltuch pedal in...it doesnt give a resistance, just goes to the floor way too easy...suggestions?

the pressure plate is what pushes the pedal back, by pressurizing the fluid. are you sure it didnt run dry at the resovour when you were bleeding it, it really sounds to me like there is still air, and if you still have the damper, thats probobly were it is

edit: or you may have a leak at the master or slave cylinder

still have the damper? why wouldnt i have the dampner? but there isnt an actual spring or something on the pedal to push pedal out?

i think there is a spring, but the spring wont pull out everything. brake fluid is non compressable, so you cant pull it out without everything else coming out too. many people remove the damper because it is sooo hard to bleed, you may have to sit there and bleed for 15+ min. check it for leaks too when you have a chance.

well i had it taken in to a shop..so i would think they bled all the stuff....but if there is a spring on the actual pedal..then thats the only solution i can come to...where is this spring located? and is it hard to locate or replace? what is the price on a new spring?

does the clutch disengage all the way, in other words, if you have it in 1st and you push the clutch in on a level surface, do you move if you take your foot off of the brake?

stick your head under the dash with a flashlight,and look at the spring. its pretty easy to see, dont know about replacement, and you will have to order it from nissan

edit: did it happen before you took it to the shop? if not, then take it back and tell them the problem

[Tx-Sx-FS]

it was like this before taking to shop..but i dont move when clutch is in and on not on brakes...but the problem is when i try popping the clutch to burn out or to try and drift a little corner...instead on the clutch engaging to let into gear...when i hit the gas the engine idles high and settles back down when the clutch actually engages instead of straight popping into gear and giving me a chirp or spin of tire or launching

so your clutch is slipping... im a little unclear here, is the pedal coming back up by itself or not? the spring itself really doesnt have that much to do with the system, it needs to be pressurized for the pedal to come back up on its own, and if its not coming back up on its own you have a pressure plate/ hydraulic problem. if it is and its just slipping like you said, then your clutch is old and worn out and you need a new one.

Your pedal not coming back up is caused by air in your hydraulic lines. This system is a pain to bleed, because of the design it is very hard to get all the air out.

I was driving from Texas to Colorado once, when my clutch pedal started not coming all the way back up. It got hard to get into gear, and my clutch started slipping. I pulled over, popped the hood, and checked the clutch fluid. It was empty. It looked like there was fluid in there, but it was just because the reservoir was dirty. I bought some brake fluid, and spent the next hour or so bleeding the clutch until it would work again. This should have been a 5 minute job, but it took an hour to get all the air out of the lines. It's worked great since then, and now the car is turbocharged, and the stock clutch holds the power just fine.

Getting to my point. It is not the spring, the spring won't pull the pedal back up. There is air in your lines. Bleed the clutch again.

If you do the dampener ditch bleeding takes 5 minutes.
