when do u know when ur clutch is out??

im thinking my clutch is out but then i really dont know. this weekend i went to sac and didnt drive my car much there. when i came back to chico (1.5-2hr drive) i noticed that my clutch was getting softer and it didnt feel the same. when i got home i didnt drive it at all. then yesterday i was going to teach my sis in law to drive stick. we went out and i started up the engine, and the clutch was even softer. it felt like i was stepping on the clutch and it was dissconnected. i tried putting it into first gear but then it wouldnt go in. i havent tried if it would go into other gears. but im thinking its my clutch thats out. but im not sure too so i just wanted to ask. thanks.

if it's "softer" than chances are it's the clutch Master Cylinder or the slave cylinder~ if it starts slipping, then the clutch is prolly on it's way out... If I Remember Correctly...

If your clutch is gone then you won't be able to engage in gear, and if you hit the throttle then the RPM's shoot up and you don't accelerate because none of that energy is getting transfered to the wheels. Also you;ll have a nice smell in the air if your clutch is going.

Most 240's clutch's get a little bit soft after being driven for a long period of time, but it should have returned to it's normal feel after having sat for a little while.

So i think it's more likely a master cylinder problem because it doesn't sound like a slipping problem.

if your clutch is going out....you will still be able to shift into gear....it just seems like you have a soft pedal.....like the other replies stated....maybe the master or slave cylinders.....or a leak....your clutch will slip when you try to accerlerate if it was the clutch.....

yeah fill it with brake fluid, be careful not to spill it anywhere as the stuff can be corrosive. While you're at it, reach under the Master Cylinder with your hand to see if it's wet at all~ if it is then obviously you probably have a leak in the MC and will need to replace it. Also check the area under it a couple days after you fill it to see if any fluid has leaked out...

make sure you bleed your clutch system when you fill it up...don't want any air bubbles in there.....there should be a little bleeder screw on the slave cylinder...same procedure as bleeding brakes....

i just replaced my master cylinder the other day. here are the steps for filling the system with fluid.

1 first poor some fluid into the m/c
2 disconnect the line from your m/c
3 connect a bleeder kit
4 have a friend pump the clutch pedel slowly untill no air bubles have to get the air out of the m/c
5 disconnect the bleeder kit and hook up the line
6 jack or raise car
7 have friend pump the clutch 10 or 20x then hold down the pedal
8 open bleeder screw on the slave cylinder for 5 or 10 sec
9 close bleeder screw
10 check m/c fluid level refill if necessary (do not let this run dry if it does you have to start over)
11 repeat steps 7-10 untill no air comes out

You don't need a bleeder kit. Without it you'll need another person or a good 'ol yardstick to push the clutch pedal down and keep it down while you're opening/closing the bleeder screw.
