1992 240sx se serious clutch problems

[BlueTyGator]

Clutch Completly Stopped Working Today!

I drive a 1992 240sx se, KA. I havn't had it long so it's pretty much stock all the way around.Last night my clutch was squeaking a little so I sprayed the lever with WD-40 (which didn't solve my problem).I was driving around today and the clutch would sometimes go down like two inches before I got any resistance. Checked the fluid, was like half full.

Tonight, I go to press the clutch and it just went right to the floor when I barely pressed it!!! I had to reach down after I stopped to pick it back up, and it just popped right up. ( 0 resistance)

Checked the fluid again, was completely dry!

Got some more fluid, filled it up pumped the clutch, no help, like its completely free, just operating on the spring.

Could the WD-40 have caused a leak like that? If so what do I need to do?

What do I have to do to get pressure back to the clutch? How do I go about bleeding the system??

Going on a trip this weekend.. Gota get her back on the road,

Please Help

Ok to bleed the clutch you need to have 2 people, speed bleeders or a vacuum pump. Fill the reservoir then pump it up until it build pressure then hold it to the floor. Have the second person under the car and open the 10mm bleeder on the clutch slave, air and fluid should come out. Pedal should loose pressure but keep it pressed down. Tighten the bleed valve release clutch pedal. Then repeat the process. Make sure you the clutch master doesn't run dry. Sounds like you are loosing fluid possibly because of a bad clutch master, sounds like it leaking possibly. Check the floor by the pedal if it wet with clutch fluid you will need to rebuild your clutch master cylinder or just buy a new one.

Found a leak in the slave clyinder

Relaced with new unit.

Spent FIVE HOURS trying to blead the system!!!

Finnally went and bought a vaccum system, Still no luck...

According to the instructions in the kit I'm supposed to just hook it up to my lower bleed point, crack the valve and go to pumping, but no luck there either...

If i pump the clutch absolutly as fast as i can I can feel a lilttle bit of pressure build up, but as soon as I slow down the clutch goes back to being competly slack.....

This is driving me crazy,

Exactly, what in the bleeding process could I be F***ing up.

Could it be that my master cylinder is bad, and that is causing me not to have any pressure on the system????

What can I do to bypass the damper box??

I'm going to try again in the morning, But a little different... let me know if I got it right or not.

running a short tube from the #1 bleed into a tub of dot3Open the bleeder and pump the system vigerouslyHold clutch in when done and tighten bleeder #1

Repeat for #2 bleeder

Or should I do the (depress clutch, open bleeder, close bleeder, release clutch) thing?

What is it I have to do to regain pressure on the clutch??Please Help!!

Thanks in advance

You can bypass the clutch dampenerbox with a stainless steel line which SPL sells. Some people just bend the hardline to the slave cyl. if you feel confident in not messing it up. Best advice I can give is just to keep at it. Its a possibility your clutch master could be bad.

Exactly, what in the bleeding process could I be F***ing up.

Here's how to bleed the system:Bleed only one unit at a time; do the clutch slave cylinder first then dothe piping connector. Get someone to operate the clutch pedal while you dothe bleeding.

1 - Have someone pump the pedal several times then hold the pedal down.2 - With the pedal depressed, open the bleeder valve to release air.3 - Close bleeder valve; now the other person can release the pedal.

You may have to repeat steps 1 thru 3 several times to purge all the air.Repeat steps 1 thru 3 for the piping connector.While you're doing the bleeding, make sure to keep the reservoir full.

The piping connector must also be bled; bleeding it can be a royal pain. As a mini-project, you can remove the piping connector; you'll be glad you did because clutch pedal operation will be much more positive.
