Welcome to the forum from Egg Harbor Township, New Jersey. Had problems with not being able to engage/disengage but it was the slave cylinder. Doesn't sound like your problem though. Perhaps what the others say about the braided line mighe be the cure. If your current line expands when at a higher temp. instead of transferring the pressure to the throw out bearing, you might need a new line. Others on the forum who have had the same problem will soon comment. Where are you located?....................Frankie
