Had that the other week myself gave a good squirt of silicon spray to all areas on pedal bar I could see that may cause it...
Now I remember I no longer have the squeak, and at the time of the clutch pedal squeak it was an unusual warm day since then it has cooled down, may depending on where you are be connected to warmer days as up here in scotland it is rather cooler than what I have seen on the news down south if not then the silicon spray trick worked as not so much of an issue in where sprayed as you get using grease....blame the weather is my excuse
