i just bought my project car. I pushed in the clutch, it was like butter, super easy. but as soon as i let out of the clutch the pedal stayed all the way down.

is this model hyraulic clutch?

 

Open the hood and take a look at the clutch mechanism. You will clearly see a master and slave cylinder.

Hydraulic.

The Factory Service Manual can be found in the FAQ For FC thread. It contains all this information and more, and is an essential tool for any sort of service work that needs to be performed on these cars.

Additionally, the Haynes service manual for the 1986 thru 1991 RX-7 (both turbo and NA) can be found at most local auto parts stores or purchased from any good bookstore (ISBN number 1 56392 007 7). It is only about $25 and is a great quick reference for things like this. Not only does it contain most of the information in the FSM condensed into an easy to read format, but it includes full wiring diagrams as well.

These manuals will answer 99% of service related questions for the car and if you intend to do your own repair work, you will need at least one of them. Preferably both, since the FSM is a free download.

 

Could be leaking fluid from the lines and has no hydraulic pressure.

 

That prob is Almost always hydraulics. If fluid is low, refill and check for leaks - master cylinder can leak inside by drivers feet as well as under the hood. slave cyl can go too. I've seen several that got air bubbles in the line and had to be bled aft fluid got low...

 

try bleeding the system first. but quite possible u'll need to replace the master, slave, and flex line. this will eliminate similar problems down the road with just replacing just one of these items as they all tend to fail eventually.

 

thanks alot guys. i get my car towed to my house tomorrow if it doesnt snow, so ill be able to bleed and refill, check for leaks, and ill let you guys know how everything goes.

 

can someone please show me where the clutch master cylinder should be bled at?

 

u have to loosen the line to bleed the master.

 

thanks guys i got it working, now have clutch pressure
