Now that the weather is starting to really warm up, I have noticed something off about my clutch pedal. When the car is first started on a cold start and driven, the clutch pedal acts normal. Release point is high and normal. Everything feels normal. No slipping. Now when driving the car to work, about a 17 mile drive, when the car gets exceptionally hot, I notice the clutch begins to become much easier to press and also requires me to press much further to the floor.

What could this be a result of and is there a known or logical fix? I don't want to start replacing parts to fix the solution until I know what it could be.

 

Check the clutch line that connects to the slave cylinder. Sometimes it bulges from heat and you lose pressure. Might also be time for new fluid and/or master/slave replacement. Both are cheap and fairly easy to replace. Bleeding the clutch is the worst part.

 

Sounds like you need a bleed, as air expands as it gets hot. Just like brakes, the hotter they get, the spongier they feel.
