Squeaky Clutch Options

[UVZ164]

Hey guys,

Recently i've had my clutch start squeaking REALLY loud and the radio wont cover it anymore. It seems to be fine for about the first 15 min of driving and then the squeak begins. It does not make a sound when i am depressing the clutch pedal. When i begin to release the pedal it will make a short squeak and for the short time there is a squeak it feels like there is some resistance sort of like a metal on metal rubbing resistance that you can feel through the pedal.
I have lubricated everything that moves in the footwell with high temperature silicone spray and lithium grease and that has no impact on the squeak. I believe its coming from the slave cylinder (see video attached). I have also squirted all over the slave cylinder and also inside it through the small opening on the rubber just to the right of the fork. When i squirt high temp grease inside, the clutch feels brand new again and will not squeak again for about 2-300km, then it comes back. I am on an original clutch and the car has done 131500km and is a 5s-fe engine.
