What kind of clutch (jobber, rebuilt, OEM?) and who put it in? Check fluid for sure, as well as slave and master cylinders, check for crudd in the lines too. maybe purge the system with fresh brake fluid. Kinda sounds like a week pressure plate or a sticky throw out bearing, did they get replaced along with the disc?. Did the flywheel get ground when the clutch was done? If not, what condition was it in? Does the clutch fade or disappear all at once? What is it like on hills?

Clutch was a new one, can't remember brand name replaced throw out bearing at the same time,I did the work. ( this is the second clutch, first one broke a spring and wouldn't disengage, but I had the same problem with the first clutch also and since I had less then 3000 thousand miles on the first clutch and the flywheel looked good I didn't have it machined,It was machined with the first clutch. replaced throwout bearing with the first one also, ) after it started to get hot in the summer and the problem came back I put a new slave cylinder in but the problem was still there afterwards. but I got by because the weather wasn't to hot. The following summer problem arouse again and then I installed a master cylinder, once again weather wasn't tearrably hot and I had another vehicle to drive so I didn't mess with it. Now this summer the problem seems worse, as I've said and I would like to really get to the bottom of this strange problem.
The problem is that when you go to release the pedal to engage the clutch ( when the problem is there ) its like the clutch won't engage, it just slips, sometimes rapid pumping of the pedal would solve the problem but the other day when it was 100 degrees outside the clutch just slipped like it was in neutral, 2 hours later after letting the truck set, the clutch worked fine.
When I installed the slave cylinder new brake fluid was installed.
I have none of these problems when the temp is below 85, I will probably take it a part again, but hate to replace parts without knowing what is bad. Thanks for your input.
