Default Soft clutch... will a bleeding fix it?

Ok, like I've said in a couple of posts, I have a buddy trying to get ends together to purchase a 944... while he's doin that, I'm finding the issues with it, and helping him determine whether or not it's worth it... so far, it seems to be. Anyway, on the test drive, I noticed the clutch was MUCH softer than my 924S... are soft clutches caused by air in the hydraulics, or : praying: is it the clutch starting to go bubye?

Thanks much...so far, things are looking good...if it's the clutch goin bubye, we'll see if they'll drop that off the price!

my clutch is soft but it is only air...so it is possible its only air. Im currently in the market for a motive power bleeder to solve things...

I'm hoping...I don't see how it could be the clutch giving up the ghost unless the PO (the only 1) was on the clutch all the time at stop lights, and it bent up the tangs on the presure plate through heat, stress, and repetition...

I recently replaced brake fliud. Bleeding the clutch is PITA. I couldn't bleed it right and now it feels much softer.

I started to bleed it having an assistant, who pushed the pedal. The system was totally empty, so we could't start pumping as the master cylinder was full of air. I decided tu suck the air through slave cylinder's bleder screw - it helped and master cylinder started to pump the fluid. The problem is that there is still air in there I cannot get rid of. During bleeding, it is very easy to suck air again to the system as the clutch output pipe in the brake fluid reservoir is relatively high - few pushes and fluid level drops casusing suction of air.

I think the only way to do it right is to use special equipment witch applies preasure through brake fluid filler cap and allows to add fluid at the same time.

There are two adjustments for the clutch pedal.

First, you need to adjust the push rod so there is about 1mm of free-play. Use a 13mm wrench to loosen the jam nut and then adjust the push rod to get the 1mm of play.

Second, there is an adjustment for pedal force. If you look at the pedal linkage you will see a spring, a threaded rod and a nut. Turning the nut one way increases pedal force (stiffer pedal), and turning the nut the other way decreases pedal force (softer pedal).

The last time someone adjusted the push-rod on my car, we got the pivot fork "stuck" in the depressed position. We had to use a screwdriver through the flywheel inspection hole cover to pop it back out. Be careful when making that adjustment.

I adjusted the push rod on mine and went to far...I know a stupid mistake, but being 6'7" and under the steering wheel I was in a hurry... so the question is: If all of the pressure is gone from the clutch push rod will it suck air into the system? and require bleeding?
