Ok recently i was driving my 80 rx7 and my clutch would start to lose pressure after about 2 seconds of holding it in. It would just re-engage. Making it possible to drive but made taking off very hard. I bled the system a million times and replaced the slave. Now there is no more air AT ALL coming out. I see the clutch slowly engage seconds after it is disengage. Any solutions? I did not see any brake fluid leaks which i thought would be the problem. Do i need a new master?

 

Always replace the master and slave together, if one goes the other is sure to be an issue.

Looks like your master is not holding pressure.

Does it lose fluid as well? It may be leaking, check for fluid under it on the
engine side of the firewall or inside under the carpet below it.

 

Your clutch master cylinder is probably leaking internally,like t.g. Farrell said,you should replace the slave and master cylinder at the same time

 

You should also replace the slave cylinder hose as well. They break down internally and can collapse. You can go with an original or a braided stainless one. I personally prefer the braided stainless hose.
