240sx clutch master problems?

[mr2lickit]

OK IDk if its the clutch master or not, but when I push the clutch pedal sometimes it very stiff (feel real good) and other times its extremely soft, making hard to get into gear. I know for a fact it has something to do with hydrualic system on the clutch.

I've replaced the slave, and have steel braided clutch line, and bleed the whole system. This leads me to believe that the master cyclinder might be going bad.

OPINIONS are welcomed

Ok I was driving today, and I lost all pedal pressure. SO I had to pull over and I took of the cap from the clutch master and started pumping the pedal. The pressure from the pedal started coming back. I don't undestand whats happening, but an explanation would be awesome!

LOL ok more info to add.... I just went on lunch break and decided to mess with my car more. With the cap off I'm able to pump the pedal until it gets stiffer and put the car into gear. After I come to a stop the pedal gets extremely soft again (Not able to put into gear unless I pump again). I'm guessing these are all signs of a dieing clutch master. So I'll be replacing this in my car during the weekend,a nd update people once again.

I would put my money on an internal leak in the master cylinder.

Where's my money at? LOL

Ok well I purchased a new clutch master, and it didn't solve anything. However, I did find the issue after a long day of work.

When bleeding the system I noticed compressed bubbles coming and couldnt figure out why, so I bent the hardline from the clutch master to the slave cylinder and noticed that line was leaking at the tip. This explains the compressed bubbles when bleeding the slave.

So now I'll be replacing the hard line, and will keep you guys updated.

I spent it on beer. Sorry!

ahhh shot me now...... OK I need help guys. I've replaced the slave, the clutch master, and the hard line (thats everything). For some reason I'm still getting compressed bubbles (looks like soda fizz). After each bleed the clutch pedal feels awesome, but after I drive the car for like 20 mins the pedal becomes super soft again, hardly engaging. So I bleed it and once again all the fluid looks like compressed air bubbles. I go through this cycle over and over again. I still can't figure out whats wrong.

If you still have air bubbles, then go back and check all your lines for cracks and make sure all the fittings are tight.
