Last night I parked my car up at the school, and when I got back to my car this morning at 6am (I was at Project Grad) the clutch is acting up. When I push down on it, it just like... stays there, not always popping back up. Also, it has absolutely NO pressure to it, but if I manage to get my car started I can still push down on it REALLY hard and shift and drive like normal.

I can only start the car in Neutral initially, not in drive or reverse or else it just sounds like I have a bad started (which I dont, I have a brand new performance started). If I start it in Neutral and give it gas, then shut the car off, I can start it in either FIRST or REVERSE. After I start it in one of these gears, I have to leave it there. If I want to go from REVERSE to FIRST (or visa versa) I must first shut the car off, then shift, then restart. If you need any more details in order to help me, please let me know.. I really want to see what everyone with experience with RX-7's thinks. Thank You!!!

if just your pressure plate was bad you wouldnt have to push down that hard, and it would slip alot, sounds like you may need a new clutch, hows the freplay on the pedal, does the clutch slip alot?

Well, i've never had a clutch 'slip', so i'm not quite sure. Once I get the car going, it shifts completely normal like it has for the past 9 months... It's just I push that clutch down, and there's NO resisitance at all! But it still shifts fine, it's just a lot more touchy. Oh, and even when I have my clutch down the car starts moving and will move forward at like 4 or 5 mph.

It's a clutch hydrolauic problem. Check and make sure there is fluid in the clutch master cylinder resiviour(sp?). I'd bet there isnt much at all in there. Fill it with brake fluid and bleed the clutch. If you're unsure how to do this, do a quick search. While you're bleeding it, check the rubber clutch line for leakage. Also check around the slave cylinder lcated ontop of the transmission, and the clutch master cylinder.

Alright great. So, where's the clutch master cylinder reservior. I'm sorry I seem like I dont know what the hell i'm talking about... But i'm just trying to learn more about FCs and Rotarys.

From the front of the car with the hood open; It is on the far right.

I'm having a bit of a problem finding a bleeding post, i've only managed to find this so far...

If it's empty, you've got a leak. Could be in the slave cylinder. Follow the line from the clutch master cylinder and you'll find the slave cylinder. They're fairly inexpensive, so replace both. Shop around for the best price.

What a freakin pimp!! Yeah, that completely fixed my problem. I just added some DOT3 Fluid and pumped my clutch 10-15 times, and it works fine. Think it may go soft again later tonight? The only problem was that my DOT fluid in my clutch master cylinder was almost completely gone.

You need to bleed it too... otherwise you'll have air in the line, which isn't really a good thing.

If it's leaking, fix it immediately, or you're going to end up with a rusty car, since brake fluid eats paint.

Pumping the pedal like crazy just turns the air pocket into a bunch of little bubbles. It will work fine for a while, but after the car sits the air pocket will form again. Pumping the pedal will get you home in a jam, but you still need to bleed the clutch.

The bleed nipple is located ontop of the slave cylinder.

Nic Pre

I don't believe it's leaking, I will look for the slave cylinder tommorrow. When I find it, do I just loosen the nipple or...? I couldn't find an article on it..

You are going to need a friend to help bleed the line properly. There is a bleed screw located on the slave cylinder (should be located right below the starter I think, but my memory is rusty). Have your friend pump the clutch pedal down with the bleed screw open. It will squirt some fluid out so be prepared to catch it with a can or something. While it is bleeding you'll see little air bubbles pop out. When the clutch is fully depressed and no bubbles pop out, close the bleed valve while it is being pumped so no air can come in. Make sure to have your friend hop out every few pumps to refill the slave cylinder so it won't go dry and suck in more air because if it does, you'll have to repeat this process all over again.

Alright! Thank you all very much, I'm glad I didn't have to go get a mechanic to look at it and pay them... ugh. Thanks again!!
