Well after replacing the master cylinder, the slave cylinder, the clutch pedal, the clutch arm, and bleeding the system A LOT, I have come to the conclusion it's time to take the clutch apart to see if that is causing my lack of disengagement. I plan on replacing the clutch fork and the clutch itself. Does anyone know where I can find the correct clutch kit for my 85 se 4 speed that won't hurt my wallet too much?
The master cylinder is set up to add fluid from the reservoir after the clutch pedal is depressed. If there is too much, the fluid bleeds through a relief valve back into the reservoir....The valve does not work instantly..so for a second or two there is higher pressure in the system, compressing air if it is in there. If you repeat the pedal motion quickly you can add more fluid and compress the air further...the end result being more travel of the slave cylinder and quicker dis-engagement of the plate. If there is no air in the system, the dis-engagement spot does not move.

The hydraulic clutch works just like the brake system. Any air in the system will compress and you will not get movement at the slave cylinder. I replaced the master and slave with parts from the local auto parts store. After struggling for days to get the system to work correctly I noticed fluid leaking from the push rod seal in the master cylinder. I threw that away and purchased the Rodney Dickman master and slave, installed it bled it, and have put 10k miles on it without a single hiccup. I don't know if you're using Rodney's parts but if you're not, save yourself a lot of problems, buy them and don't look back.
So I've seen a couple different sizes for the clutch plate for the 4 speed. I've seen that it's supposed to be the 9 3/4" plate or the 9 1/8" plate. My thinking here is that maybe the bigger size is actually for the 5 speed? Anyone able to help with this?
First thing to look at is how much movement you get on the lever on the trans. Hold a scale up to it while someone pushes the clutch pedal. Should be around 1 1/8" movement. If it is that much it is then time to look at the clutch assembly.
