I am a long time member who due to lifes changes has not been on this site in a few years. I have a 65 K Code which I have owned for 16 years. While driving it yesterday I heard a "pop" sound (which I also felt) when depressing the clutch pedal to make a shift. There is now no real resistance for the first half of the pedal travel when the pedal is depressed, then it feels normal from there to the floor. The car still drives and shifts ok and the pedal does return to regular height when released but something obviously has broke. Any ideas as to what has happened/let go? I have not have a chance to look at it yet. but will be doing that in a day or so. Thanks in advance for any thoughts on this.
