The other observation I have made with clutch discs is that the "organic" compound discs like you are using have a slight chshion built into the disc. If you look at how it is made you can see how there is a slight space between the clutch materiel on each side and the driven plate in the center. This allows the disc to compress about .030 (on the one I measured) so not only do you have to release the pressure plate you have to release it more than the disc compresses or there will be drag on disc from the spring built into the material mounting. The puck type designs do not have this cushion built in. Can't tell you if switching would solve your problem but it definately will give more clutch release than with the organic type. Down side is that engaugement is not as smoothe bcause the cushinon is not there in the puck type discs. Larry

Picture of the cushion built into the organic type clutch:

Now that you have it off, gently push in the clutch so that the slave fully extends, then measure how much rod is sticking out of it. After you put the arm back on and the rod in the socket, measure it will the clutch pushed in and make sure that distance is less than the first measurement. If it is the same then you are hitting the end of the travel. Larry
