Hey guys, Im using my FB as my winter car right now cause my FD just blew a apex seal. My FB is a nice car i re did all the panels on it, new paint. I love it, its a beaut of a car.

Its been pretty much hitch free for the 3 years ive had it, except now. Before the Xmas break, i was having clutch issues, id have to pump the clutch soo much just to ever get it into gear, usually 1st would be where it would have the most problem. I drove like that for a day. I then checked the fluid in the clutch, and it was like bare, zip , no fluid. So well that made since. i filled it up, and it was fine.

I went for the Xmas break to BC for a week, when i got back on the 2nd. (car sat out for 1.5 weeks, no driving, just sat) i went to go drive it, and its almost back to normal, i have to pump the clutch to go anywhere. The fluid is full. Its weird, if i push in the clutch, then pull it out a bit, i totally loose it. Its totally dead. I actually only have about like 2-3 inches of play when i push in the clutch, usually when go to start off from a red or w/e i just push in the clutch, rev it up a bit, and keep the clutch floored and it will just release it by loosing pressure or what ever its doing.

I searched before i wrote this thread, and i seen people talking about a "slave" i have no idea what that is. But if you guys have any info, or what i should go check right now id really appreciate that, cause i need this thing hopefully fixed before work tomorrow!!!

Slave cylinder is on the transmission. Master cylinder is on the firewall leading to your pedal. Do yourself a favor and replace both.

How clean is your fluid? I know you just added some but how clean would the stuff be thats already in there? Mine is currently black, it should be clear, and the pedal has pretty much no feel to it at all. Try bleeding your fluid altogether, and then download the FSM from Troichoids sig, and look in there for the clutch slave. I'd tell you what it is, but I'm not entirely sure either.

The clutch slave could be the culprit, they are easy to install and can be had or ordered from the internet/parts shops. Mine went bad and had about the same characteristics.

well i added Dot3 Oil to my Clutch, which it asks for and it was black already. Any other possible thing could be wrong. If i go to where the clutch engages on the transmision, and pull it back, oil squirts out of the clutch oil tank. Dosent seem bad, but just seems like its working.

I had the same symptons. Your slave is more than likely going. I'd recommend you replace it and bleed the system. I just ended up replacing my entire clutch system (new master, slave, hydraulic line, and stainless steel braided line).

I went through the same thing last year. Do yourself a favor and replace both the slave and master cylnders. Both from black dragon will be less then $100 brand new and it is an easy job. Trust me it will be worth it.

^ never trust anyone who says trust me, but yeah if your clutch hydraulics havent been overhauled its time

^ Trust me, Mike knows what he's talking about.

You can get away with just replacing the 'slave', aka 'clutch release cylinder' as per haynes manual, just bleed the system to get new clutch fluid in before you put the new slave cylinder on then bleed again. This is what I did because I needed the car the next day and was broke at the time.

so where can i get this slave, from a part source or ahy of those, or is it indeed a order me part?

Any auto parts store.

NAPA is where I got mine.

ah really! wells thats awesome! What exactly do i need to ask for when i go there? and is there a write up any where or can anyone give me some insight into replacing it?

waysrx7

Simply ask for a clutch slave cylinder for whatever year rx7 you have.
It's easier to change your slave cylinder than to change brake pads, but here is a link for you - http://www.wankel.net/~krwright/file...7(6)clutch.pdf.
basically just unbolt it from the tranny ( 2 bolts - max of 2 min to get off ) then unscrew the slave from the hydraulic line, screw the new slave on bolt it back up. then bleed the system.
If you really don't have much clutch left you can add a couple washers between the slave rod and where it connets to the tranny clutch fork thing.

as ways said SUPER simple. it might even say in the FSM im not sure, definetly does in the HAYNES manual which is worth picking up IMO. Just make sure you try not to get clutch/brake fluid on any painted parts when you take it off as paint does NOT like brake fluid. Also if you top up and bleed the system make sure you use compatible fluids (meaning dont use DOT 5 because chances are its either dot3 or 4 in there and 3 and 4 do not mix with 5 if you didnt know)

i'd say since you're not losing fluid that your master cylinder is bypassing. rebuild it.

waysrx7

^^ you don't need to lose much fluid to have the slave go bad because a bad slave will allow air into the system which causes the dead pedal. Right after my slave went I bleed the system because there was air in it but the slave kept allowing air in so I had to replace it.

^ +1.

Replace the slave. Easy as pie. Soak the fitting going into it with PB Blaster to ensure it isn't frozen stuck in there.
