High temperature clutch engagement

[Gone in 60]

Hi all,

Just polling the group to see if anyone else notices the same thing my car has been doing.

When the weather is hot, over 95 or so degrees, my clutch pedal seems a bit heavier. I can feel more fluid resistance in the pedal. Doesn't matter how hot the engine is, this is relative to ambient temp.

This is my first non-cable operated clutch car - didn't get that sensation with a cable.

Thanks!
