I have a Mcleod twin disc clutch in my '64 Polara 500. Everything is new, but I've adjusted the clutch three times already, each time after a fairly long highway trip. Last time I went about 25 miles, and could hardly get it in reverse because the clutch would not release. I just checked it cold and the pedal free play is 2 1/2". It was only about 1/2" before. My brother has the same clutch in his '70 RR and has had no problems with it. I read some of the other posts on here and saw nothing about being worse when the car is hot. It is either just slowly bending something, or it is related to being hot. Thing is, it works fine now. Too cold to try it out hot. Is there something to break in? Anybody have any ideas on this?
