hello my clutch has stopped working on the troublesome 90 . lets start with i got a flat pedal but the master cylinder is full. I took the slave off the flywheel housing and it seems to me that the fork is jamned.how could this of happened thats why i got no pressure on the clutch because the push rod is not really touching any thing. Could it be the throw out bearing knarcked i dont know any suggestions before i pull the gear box would be appreciated thanks
