Default Clutch help please.

I bought a 95 with a weak clutch. I am thinking, before it gets cold or the clutch takes a dump and breaks something else, I would replace it.

What are your recommendation for a cruiser/daily driver car. Her birthday is 03/22/95, if that makes a difference in part fitment.

Please post the part numbers if you have them.

I am not worried about soft pedal, I just want a good clutch that will last another 111k miles.

Thanks in advance.

Well, it may or may not actually be your clutch. Depending on the symptoms. If your clutch is bad, the tell tale is that when you accelerate, the engines revs but the car doesn't move any faster.

If it's your just a soft pedal, that is an entirely different set of circumstances.

First check the hydraulic fluid level in the resevior located on the driver side under the ECM and over the battery. Remove the ecm by unscrewing the 2, 7mm bolts, slide it out and move out of way. You will see the resevior. If it's low, you may have a leak, either in the line or more likely the slave cylinder. If you have the original slave cylinder at 111K, you are one of the lucky ones.

If it's full, then your clutch master may be going out. Or it could be a worn clutch fork and/or fork ball stud. This requires removing the trans and bell housing to check. If this is the original clutch (doubtful) it needs replaced anyway I'd bet.

spec clutches and lightweight flywheels are quite nice. Pricey but great customer service.

If you find the clutch fluid is low, do two things:
1) gut yourself under the dash and check to see if you can see any fluid where the clutch pedal rod goes through the firewall. Pull the rubber boot off the end of the master cylinder. If you have fluid there...the master is leaking....replace.

2) Get under the car and look for leaks around the slave cylinder. Unbolt the slave and lift up the boot where the rod is. If fluid is present, you found the leak. Replace the slave.

Now if the problem is the clutch is beginning to slip...then you get to remove the driveshaft, transmission, bell housing, clutch...and hope the dual mass flywheel is good. If it is leaking...then you might find a used one...good luck on that....or you get to do lots of reading to determine which of the single mass flywheel and new clutch sets you want.

For a daily curiser...in my opinion...a lightweight setup is not the way to go. You would want the heavy steel flywheel and clutch set. But this will be up to you to decide.

Oh and replacing the clutch takes quite a bit of time. That ZF trans is one heavy sucker. Be sure to have a trans jack that has a belt to go around it to hold it onto the jack.
Then there are the four bolts on the member between trans and diff...lots of fun getting to those.

And then there is the......and the......, and also the......

You get the picture.

Good luck.

The Clutch isn't slipping, my slave cylinder is good and works fine, and by soft pedal, I meant, I don't mind a stiff clutch. I have a Mcleod twin disc behind my 408 LS stroker in my Z28, but this car is going to be more of a daily driver/cruiser and it doesn't need a twin disc or any heavy duty set up.

I'm wanting some recommendation on good clutch kit for this car, I have been out of a C4 since 2002.

Thanks guys for all the help on everything else.

If you go to a Chevy dealership and have them replace your clutch, this is the one you would get. I have had one of these in my car for the last 110K give or take, though it's my next project, it's still doing it's job. I have a '96 LT4 with a hotcam and modified exhaust. This is a very driveable clutch. Just don't ask me about slave cylinders if you don't want me to cuss.
