So,

I'm starting to begin to figure out the problems for my rx7, I've already replaced the heater hose! (GO ME!) So I come to a stop light tonight and think, well, I've never actually launched the car only gone from stops so let me drop it and see what happens.

I rev it up to about 3500 rpm and drop the clutch and mash the gas and guess what it does, something weird.

The revs go up to 5k rpm and then the car starts moving, not fast like it usually does, then I go to shift to second at about 7000 rpm and it does the same thing again, 5k rpm then it goes again with no problem...I figure its a slipping clutch so I slow down punch it and shift and it has no problems.

Is the clutch in it bad?

Ok,

I think I figured it out, my master or slave cylinder is apparently going out because I launched the car another time and it did just as it was supposed to.

Now, today on the way to pick up my girlfriend my clutch pedal went STOMP to the ground and didn't come back up unless I pulled it up...fun fun. There's no leaking fluid but apparently something’s bad, I'm hoping it's the master cylinder that way I didn’t just waste $60 on a new one.

One thing to do is to check that the slave is working properly and pushing the clutch fork. If not then check that fluid is getting from the master cylinder to the slave. If no fluid, the master cylinder is the culprit. If the slave is getting fluid and not pushing in the fork, something is wrong with the slave. If both are doing their job, the problem is the pressure plate or the release bearing going out.

Well, the slave pushes the fork out just fine until you use the clutch a little too much, I just bought a new master so we'll see on that end.

I didnt see any fluid leaking out anywhere and the line looked fine.

Replaced the Master Cylinder, didn't get the chance to bleed it...



The clutch defintley changed though because it went from partially engaging to not engaging at all leading me to believe that the Master was the case.

Tech_Greek

Yeah, I should of probbaly just bled it in the first place but hey...who gives a **** right? Now I don't have to worry about the Master Cylinder breaking down!

Just be wary.. It's pretty common to install a new cylinder into the clutch system (either master or slave), and the new pressure from one damages the seals on the other. A lot of people recommend changing them at the same time, to avoid problems. If you're on a budget, then when you get around to it, replace/rebuild the slave cylinder.

Then again, you may be lucky and not have a problem.. Just keep your eyes open for it.

It seems to be doing fine so I'll keep an eye on it...
